Hey, I hope this is the right place to put my report since my problem concerns an xfce-from-svn ebuild (from overlay.gentoo.org/proj/xfce), I didn't find another place to report. Anyway, I was installing xfce from the ebuilds that day and ran into trouble with emerging xfce4-panel, a configure check failed because of a missing dependency to xfce-mcs-manager. Actually, a non-svn version would have been okay (but all necessary versions were keyworded in portage so I didn't have it installed yet), but it wasn't at all covered by the ebuild. Might be that another ebuild would have taken care of that, dunno. All I know is, it didn't work and a patch that I'll attach made it work. Comments on this (or submitting as revision 5 *g) very welcome. (PS: The ebuilds are great, thanks a lot!)
Created attachment 99397 [details, diff] Diff to current svn version (r4), adds necessary dependency I added the version number according to what configure spit out, hope that is alright.
Fixed in SVN, thanks for reporting.
