[Pythonmac-SIG] Problems with matplotlib

[Larry Meyn]

Michael,

Thanks for taking the time to reply to my question.  You are the second 
person to suggest completely removing  the old libraries and 
re-installing, which in fact was the needed solution to the problem.   
As for your suggestion to use fink, it is something that I have been 
avoiding as it doesn't always seem to  play well with standard 
installations.  I was very tempted to use fink in order to get a 
working matplotlib, as installing freetype2, libpng and zlib from src 
seemed to be a rather daunting task.  Fortunately, the  i-Installer 
(http://ii2.sourceforge.net/) distribution application for TeX on OS X 
is a viable alternative for installing freetype2, libpng and zlib.
