Subject: Allow binary packages to be installed with --usepkg even when there is no ebuild... 
X-Git-Tag: v2.1-r2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a9dc0a4ce8de8ff77ced4c2d169b739578eb64c0;p=portage.git

Allow binary packages to be installed with --usepkg even when there is no ebuild in tree (but not when there is a matching ebuild in the tree that is masked).  See bugs #55871, #135834, and #140694.  This patch is from trunk r3826:3829 and r3907.
