Comment (by jpflori):
I think the problem is that somehow loading the mercurial module osutils
triggers loading some Mac OS framework mysterious stuff which itself wants
libpng, but Apple is so nice they decide to prefix their symbols with cg
in their system wide libpng.
Unfortunately its ours which gets picked and we do not prefix the symbols
with anything fishy.
Whence the "fix" to remove libpng.dylib so that when the Mac OS graphic
thing looks for libpng it does not find ours.
Hopefully the spkgs we build and which need libpng ling to libpng12 and
finds ours rather than the Mac OS X, at least it seems to be the case on
Linux.
