I guess I don't have pkg-config installed. Is this a requirement? I haven't
had it installed before?

I think it's just finding the wrong version of libpng. For whatever reason,
it has decided that an old version in
/Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libPng.dylib is the proper
version, despite there being a newer version in /usr/local/lib.

Is there any way I can rearrange the search path so that it finds the
/usr/local/lib version?
