Default x11-libs/qt-3.3.8b fails to build with libpng-1.4 because a patch is not being applied

Fortunately, in February a patch to fix this issue
(files/qt-3.3.8-libpng14.patch) was added to the overlay.

Unfortunately, even though the patch is there, the qt ebuilds in the
overlay don't apply it.

Please add epatch "${FILESDIR}/qt-3.3.8-libpng14.patch" to the qt:3 ebuilds.


I've read something to the effect that libpng-1.4 is causing all kinds
of headaches even in mainline Gentoo (even without kde-sunset). It's
got me nervous to update... I still remember about ten years ago when a
libpng update completely hosed a FreeBSD desktop I was maintaining then.
Here we go again! :-/

Yes, indeed the new libpng-1.4 is breaking a lot of packages (think i read
sth. about relation to not using --as-needed or so on some gentoo-related
blogs ).
After fixing the qt-3 ebuild it still broke bluefish and some others....

For the time being i would suggest masking libpng-1.4... until this is
resolved.
