Re: [gentoo-dev] Autodep project

[justin]

Hi,

if this tool works like it supposed, it will be very handy. But the
current ebuild/buildsystem suffers from disrespecting CC and failing
with forced as-needed, isn't strict multilib capable and
byte-compilation of python modules. Please find attached a hacky patch.

thanks justin
