Fortunately, the fix for the errors (the deprecation warnings can be ignored for now) is pretty trivial.
Created attachment 231299 [details, diff] qt-3.3.8b-png14.patch Fix for compilation errors. In libpng-1.4, the "trans" and "trans_values" fields have been renamed to "trans_alpha" and "trans_color", respectively.
Sorry, but kde-sunset is user maintained overlay. You can contact the maintainers from gentoo-desktop mailinglist.

Unfortunately, the gentoo-desktop mailing list apparently thinks my emails are spam (even though I followed the instructions at http://www.gentoo.org/main/en/lists.xml). Could you please post the following message to the gentoo-desktop mailing list? (There is a better patch already in the overlay, it's just not being applied by the ebuild.) ---------------------------------------- x11-libs/qt-3.3.8b (from kde-sunset overlay) currently fails to compile with libpng-1.4 because some structure fields have gotten renamed. Fortunately, there already exists a patch to fix this issue (files/qt-3.3.8-libpng14.patch) and it was added to the overlay in February. Unfortunately, for unknown reasons, the qt ebuilds in the overlay don't apply that patch. Please add epatch "${FILESDIR}/qt-3.3.8-libpng14.patch" to the qt:3 ebuilds. -Alexandre Rostovtsev ----------------------------------------
