libpng 1.5.0 has issues and is breaking builds

[Srinath Vadlamani]

Current warning on libpng website:http://www.libpng.org/pub/png/libpng.html

seems that many ports are not building because of another issue dealing with incompatible png.h.

I looked at the bug reports but I don't see one that casts this png.h as big of a problem as it may be.

Any ideas on how to fix this?
