Created attachment 231031 [details, diff] patch for working with libpng-1.4.2
Created attachment 231033 [details, diff] update ebuild to apply patch
It's already fixed... 12 Mar 2010; Samuli Suominen <ssuominen@gentoo.org> povray-3.7.0_beta32.ebuild, +files/povray-3.7.0_beta32-libpng14.patch: Fix building with libpng14.
The patch on 12 Mar 2010 is only for the version 3.7 betas. 3.6 is the stable release and is what I have to use on an otherwise ~arch system. After upgrading to the new libpng it fails as described. The attached patches fix the issue.
