The first suggestion failed with the same error, while the same suggestion
worked up through the last step (make installers) which fails with the same
error.
I decided to try Tommy's suggestion of just figuring out how to compile
libpng as a universal binary. The way I did it was to run the configuration
script as:
./configure --disable-dependency-tracking
and then to manually edit the Makefile. To CPPFLAGS and LDFLAGS I added
-arch i386 -arch ppc
Running make and sudo make install successfully built a universal library
for me.
After deleting my old MPL egg, I import matplotlib successfully and the
version number is as expected (0.98.6svn).
However, when I try to import pyplot, I get the following exception
traceback. Any suggestions on how to fix this?
Thanks again!
