The sensitive root folders (like /usr) are hidden from the Finder so
that it's hard for someone that doesn't know about them to
accidentally delete/move something sensitive that's supposed to stay
put. You can get around this easily either with Terminal or Finder
itself.

If you're comfortable with Terminal:

-Open Terminal
-Type "cd /usr/X11R6/lib" (without quotes) and then push ENTER
-Type "ls libfreetype.6.dylib" (without quotes) and push ENTER
-Look at the output. It should spit back "libfreetype.6.dylib" at you.
If it spits back nothing, the file is missing.

If you're not comfortable with Terminal:

-Open a Finder window
-From the menubar, click Go -> Go to Folder...
-Type "/usr/X11R6/lib" (without quotes) and push ENTER
-Look in the list of files yourself to see if the file
libfreeype.6.dylib is there.

Also, for future reference, when getting help on a mailing list, make
sure to hit "Reply-all" instead of just "Reply" so that the
conversation stays on the mailing list and doesn't turn into a private
email correspondence between just you and one other person.

So I have downloaded matplotlib I’m sure, but when I type “cd /usr/X11R6/lib” into the terminal is says “no such file or directory.”
Do you know what this means?

Thanks for all your help,

Katie

Could you try just typing "cd /usr", then "ls" and checking what
folders are in there? Is there an X11 folder in there at all?

You can also re-set finder to show you the hidden dirs -- I always have mine set up that way. The easiest way is to use a utility called "TinkerTool", but you can also change the finder setting with the command line:

Either way, the problem is that matplotlib is trying to access a file
somewhere that doesn't exist (and needs to exist). Make sure you have
X11 installed on the computer (simple spotlight search should turn up
the app frontend), and then install the X11 package from Apple's Xcode
developer tools (available on the install discs for the operating
system or online from developer.apple.com in the downloads section of
the members site with a free ADC account. If you end up downloading
the tools, keep in mind that Xcode Developer Tools 2.5 are the latest
working version for OS X 10.4, and 3.1.1 is the latest working version
for 10.5 (since it's a large download). Once you're sure you have the
X11 tools installed, remove matplotlib and do a clean install.

Note: If you don't have X11 installed at all (not just the dev tools,
but not even X11 itself, which would mean you're running something
pre_leopard I assume), you can install this as one of the optional
components of your OS X install disc.

If you're comfortable with Terminal:
-Open Terminal
-Type "cd /usr/X11R6/lib" (without quotes) and then push ENTER
-Type "ls libfreetype.6.dylib" (without quotes) and push ENTER
-Look at the output. It should spit back "libfreetype.6.dylib" at you.
If it spits back nothing, the file is missing.
If you're not comfortable with Terminal:
-Open a Finder window
-From the menubar, click Go -> Go to Folder...
-Type "/usr/X11R6/lib" (without quotes) and push ENTER
-Look in the list of files yourself to see if the file
libfreeype.6.dylib is there.
Also, for future reference, when getting help on a mailing list, make
sure to hit "Reply-all" instead of just "Reply" so that the
conversation stays on the mailing list and doesn't turn into a private
email correspondence between just you and one other person.

Thanks! I don't know how to find the /usr/X11R6/lib folder though. I
searched for it, but I couldn't find it.

It appears that matplotlib is having trouble finding the freetype
dynamic lib in your /usr/X11R6/lib folder when it references it. I'd
check that folder to see if the dylib is there. If it isn't, reinstall
the X11 dev tools. If it is, something is wrong with the dynamic lib
opening, so I'd recommend removing matplotlib from your
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages
folder and doing a fresh build/install.

Oh, I figured it out. It's not there. How do I reinstall the X11 dev

I have some notes on how to install on OS X that covers this -- see

  http://ipython.scipy.org/moin/Py4Science/InstallationOSX

The explanation on the xcode dev tools is brief, and reads::

  install gcc and other developer tools

  Install XCode developer tools from the Leopard install CD under
optional packages. Verify the install -- check for a working gcc

   > gcc --version
   i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)

  If you don't have the cd (or not a very recent one), you can get
XCodetools from the Apple Developer Connection:

  http://developer.apple.com/tools/download/

  you may have to join (for free) and login.

Hope this helps,
JDH
