I was able to build matplotlib on 64-bit OSX 10.5 just using setup.py. There were some glitches, but if I remember correctly they were due to the underlying libraries being 32-bits rather than 64-bits. One thing to try is to run "otool -L /Library/Python/2.6/site-packages/matplotlib-1.0.svn_r8034-py2.6-macosx-10.6-universal.egg/matplotlib/_png.so" to find out which libraries _png.so uses, and to make sure they are 64-bits versions.
