ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/ft2font.so, 2): Library not loaded: /usr/X11R6/lib/libfreetype.6.dylib

What version of OS X are you using? How did you install Python and
Matplotlib - did you get a precompiled version, or install via Fink or
MacPorts, or compile it yourself?

Here's a wild guess: since /usr/X11R6 is just a symlink to /usr/X11, the
file /usr/X11R6/lib/libfreetype.6.dylib has an "install name" of
/usr/X11/lib/libfreetype.6.dylib, and perhaps the dynamic linker doesn't
like the mismatch. Do the following commands fix the problem?

cd /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib
cp ft2font.so ft2font.so.bak
install_name_tool -change /usr/X11R6/lib/libfreetype.6.dylib \
/usr/X11/lib/libfreetype.6.dylib ft2font.so

If not, copy ft2font.so.bak back over the modified ft2font.so to prevent
the attempted fix from breaking anything else.

I’m using Mac os 10.4.11. Python is included in mac os. Matplotlib I installed from a precompiled version.

I tried doing what you suggest, but it didn’t work. I still can’t import pylab. There’s also a file called libfreetype.6.3.dylib there. I don’t know if that helps.

Anyone have any help to get pylab working? Should I reinstall? What method should I use?

I tried doing what you suggest, but it didn't work. I still can't import pylab. There's also a file called libfreetype.6.3.dylib there. I don't know if that helps.
