This occured after fully updating my Gentoo system (~x86). I've tried various older svn builds up to 2 months ago but they all have the same issue for me. Hopefully someone can look into this, thanks!

This was already looked into at: http://bugs.gentoo.org/380127 And reported to upstream here at: http://trac.xbmc.org/ticket/12001 http://trac.xbmc.org/ticket/11977 I'm not sure what else we can do, other than wait for upstream to finally act on it. Should be pretty embarrasing from them for the project to not compile on mainline, stable libpng.
