There are no pixmaps on the buttons in the playercontrol window of aviplay. It seems that the install does not copy the /usr/share/avifile0.7 directory (which should contain the images for the butons). The fix involves the change of a single character in the ebuild. The line in src_install() which reads: make prefix=${D}/usr datadir=${S}/usr/share install || die is changed to: make prefix=${D}/usr datadir=${D}/usr/share install || die
