USE flags with which it's built: [ebuild R ] media-libs/imlib2-1.4.4 USE="X png -bzip2 -doc -gif -jpeg (-mmx) -mp3 -nls -tiff -zlib" but without a pkg-config installed we have this in log: checking whether to enable png support... yes ... checking for pkg-config... no ... Configuration Options Summary: Image Loaders: JPEG....................: no PNG.....................: no Reproducible: Always
Created attachment 280063 [details] build.log
But looks like it's optional as it doesn't fail :-/
With _enabled_ png USE flag I expect it to be built with png support, so it should pull required dependencies e.g: DEPEND="${RDEPEND} ... png? ( dev-util/pkgconfig ) ...
thanks ... should be all set now http://sources.gentoo.org/media-libs/imlib2/imlib2-1.4.4.ebuild?r1=1.10&r2=1.11
