[DRE-maint] Bug#514126: unable to install gems as non-root user

[Antonio Terceiro]

The problem here is not the permissions of /var/lib/gems, but the fact
the a non-root user cannot install gems into her $HOME/.gem anymore,
which used to work with rubygems 1.3.5-2. Uninstalling gems from
$HOME/.gem, on the other hand, seems to work.

==> 1.3.6-1 installed, unable to install as non-root
