Installation Problems on Mac OS X

I'm in the process of migrating from Windows to Mac OS X and doing my first round of installations from source code in the process. In trying to install matplotlib I get the following error:

/usr/bin/ld: for architecture i386
/usr/bin/ld: can't locate file for: -lpng
collect2: ld returned 1 exit status
/usr/bin/ld: for architecture ppc

Can anyone tell this novice Mac installer what this means and how to go about fixing it?

Building matplotlib requires linking against libpng and freetype. The
error you posted is just saying that libpng can't be found. Building
matplotlib correctly on osx and windows isn't for the feint of heart.
Have you tried the pre-built osx binaries available for download on
sourceforge?
