repoman says: [...] DEPEND.badindev 1 media-gfx/jpegoptim/jpegoptim-1.2.2.ebuild: ~ppc-macos(default-darwin/macos/10.4) ['media-libs/jpeg'] RDEPEND.badindev 1 media-gfx/jpegoptim/jpegoptim-1.2.2.ebuild: ~ppc-macos(default-darwin/macos/10.4) ['media-libs/jpeg'] digest.missing 1 jpegoptim deps on media-libs/jpeg, that has no ppc-macos-flag. Either remove it from jpegoptim or add it to jpeg.
Sidenote, jpegoptim-page is dead, this is the new url: http://www.kokkonen.net/tjko/projects.html
ppc-macos moved to prefix.
Thanks, I've now fixed the url, so everything should be okay.
