There is a missing useflag (libpng) in x11-wm/pekwm-0.1.5. If you want to apply a png based theme it won't work because pwkem have to be built with libpng support. This function is missing in the ebuild. Can somebody please fix this?
Fixed... media-libs/jpeg and media-libs/libpng are now dependencies and the appropriate lines have been added to the econf line in src_compile. As a result of this bug, I also realised imlib2 isn't supposed to be a dependency. Thanks for the report!
