well, when I tried:
easy_install matplotlib-0.98.5.1-py2.5-macosx.egg
it again did the sillyness of installing it, then going and downloading
the source.
However, I took the "macosx" off the name, and it worked fine:
easy_install matplotlib-0.98.5.1-py2.5.egg
But then it's a bit hard for users to know that it's an OS-X egg! Maybe
it could be put on the download site as:
easy_install matplotlib-0.98.5.1-py2.5-macosx.egg.zip
and unpack it to one with the shorter name. (even though *.egg files are
already zipped!
Perhaps we need to figure out what the heck is wrong with easy_install
instead! (Not I want to dig into that code!)
However, once installed, I tried to run it, and got libpng issues --
aaarrgg!:

I'm running python 2.5.2 universal framework build, on a PPC running
OS-X 10.4
Here is the otool ouput on _png.so:
otool -L _png.so
_png.so:
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current
version 1.2.3)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0,
current version 7.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.3.10)
/usr/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 1.0.0)
/usr/lib/libmx.A.dylib (compatibility version 1.0.0, current
version 47.1.0)
so it's not linked to the dynamic libpng -- hmmm.
