That should help. Yep, I was. That was the binary recommended first on the wiki (at with a note at the end that some have had problems with it that do not appear related to my problem). Using the universal binary at the att site fixed my problem, and I updated the wiki at http://www.scipy.org/Installing_SciPy/Mac_OS_X. Now for my next problem: I built zlib, libpng an freetype from source and I get a ld: warning in /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libpng.dylib, file is not of required architecture error when building mpl. Is there an easy way in the configure/make/make install cycle to tell the compiler to build universal binaries? Alternatively, can I instruct distutils to simply not provide the -arch ppc build? I can see how this will be a problem down the road, since any non universal library I install on my system will potentially break my builds. Thanks, JDH
