Running "equery hasuse gtk" fails: !!! Invalid CPV: 'app-arch/xz-utils-4.999.9_beta-r00.1' Apparently, this ebuild isn't correctly named (looks like it) and/or gentoolkit CPV regexp are too strict. I'm not sure if it's an equery bug, or xz-utils is just wrongly named ? If it's an equery one, we should CC tools-portage@g.o maybe. Anyway, I can't reproduce this bug with older gentoolkit version (stables one, on real gentoo x86)
Woopsie, I cc-ed them already. Sorry, remove yourself if I shouldn't have done that.
