The image module uses _png. Even the vector backends need raster images. We could move the import into the method when it is actually called, since we actually embed the images directly into the ps and do not go via png. >> Could you also test the mpkg zip file -- I am curious if that shows >> the same png problems for you. > > same errors as the egg. > > Can you test on PPC?

I *may*, repeat *may*, have had a breakthrough here. It appears that setting the universal flags on the make line is not enough -- they must actually be exported (as Charlie's original notes indicate). Please try again with the new OS X binaries at https://sourceforge.net/project/showfiles.php?group_id=80706&package_id=278194&release_id=646644 I didn't do any clever renaming of the egg this time -- just focusing on the png name manging error.

Re: [Matplotlib-users] [matplotlib-devel] os x egg fubar?
Another note:
I was wrong, if I easy_install the egg without the -macosx from scratch,
it fails with:
Searching for matplotlib-0.98.5.1-py2.5
Reading http://pypi.python.org/simple/matplotlib-0.98.5.1-py2.5/
Couldn't find index page for 'matplotlib-0.98.5.1-py2.5' (maybe misspelled?)

But now I just ran:
easy_install matplotlib-0.98.5.1-py2.5-macosx.egg
and it worked just fine -- this is weird!

same errors as the egg.
Can you test on PPC?
I recently had a problem with a wxPython extension -- it build
Universal, but only worked on Intel. It turns out that the wxPython
binaries were compiled differently on PPC and Intel -- using an older
version of gcc on PPC (for 10.3 compatibility maybe?). Anyway, it was a
mess, but we fixed it by compiling the extension separately with a bunch
of different flags, then lipo-ing the two binaries together.
Could anything funky like that be going on here?
