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.

Fingers crossed,
JDH
