This is a build time dependency of app-editors/mg. In the tree since four months, without any bugs reported. Target keywords: alpha amd64 hppa ppc sparc x86 Test plan: <http://wiki.gentoo.org/wiki/Project:Emacs/Test_plans> Thanks in advance.
Stable for HPPA.
mg-20140220 has dropped the dependency on clens, so this is no longer needed.
