Subject: Use realpath(__file__) to locate whole portage.
X-Git-Tag: v2.2.0_alpha169~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=84d405e6f79a04a6d2bfc4713dd80d48453d983a;p=portage.git

Use realpath(__file__) to locate whole portage.

Use realpath(__file__) so that python module symlinks in site-packages
are followed back to the real location of the whole portage
installation.
