This seems to be an ABI incompatability issue, and I've been able to reproduce
this error. One temporary measure would be to require a libpng version below
1.2.12. Upstream libpng knows about the ABI incompatability issues as stated on
their mailing list, however, upstream gif2png doesn't seem to know. 

Created an attachment (id=91163) [edit]
gif2png-libpng.patch

Found this patch on the libpng ML archive at
http://sourceforge.net/mailarchive/forum.php?thread_id=10199493&forum_id=43850
(thanks to Thomas Klausner).

It resolves the >=media-libs/libpng-1.2.10 issues and compiles and runs as
expected on my x86 box. The aforementioned post raises some doubts about the
patch's effect on gif -> png comments; however I haven't run into any problems
so far. So please test!

Created an attachment (id=91164) [edit]
gif2png-2.5.1-r1.ebuild

Ebuild to apply the libpng patch attached previously.

Yeap, compiles fine here.

Thanks, I just added the patch to 2.5.1, it worked fine for me.
