Re: [gentoo-user] Multilib help

[James Stevenson]

The easiest way to fix this issue is to figure out which libraries you need
and then stipulate that you want the x86_32 version of that package in your
accept_keywords file. Check the Gentoo wiki for the software you are trying
to run for hints on what libraries you need.
