Subject: pkg_use_enabled: return early for built pkgs
X-Git-Tag: v2.2.0_alpha41~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a40c1905e53d3af20df6d4f940e1235551a6840e;p=portage.git

pkg_use_enabled: return early for built pkgs

Built/installed packages have frozen USE settings, so there's no sense
in considering them for autounmask USE config changes. They'll simply
be rejected by select_package, and an unbuilt ebuild will be selected
instead. This will fix bug 371423 by avoiding unnecessary use_reduce
calls on the deps of installed packages.
