IIRC, cups has no other dependencies, so I'd think it would be just
    <repository type="tarball" href="http://www.cups.org/"; />
    <autotools id='cups' autogen-sh="configure">
        <branch module="software.php?VERSION=1.6.1&FILE=1.6.1/cups-1.6.1-source.tar.bz2" version="1.6.1" />
    </autotools>

Oh, it got fixed in short order. No worries about that. But feel free to pitch in...

No, but ISTR Behdad decided that he couldn't support ATSUI any more. He thought that there was enough of CoreText already in Tiger so that it would work, but I guess not. You'll have to build meta-gtk-osx-freetype before meta-gtk-osx-core. That will provide the pangofc2 backend.
