15     # This function simply returns the desired lib directory. With portage
16     # 2.0.51, we now have support for installing libraries to lib32/lib64
17     # to accomidate the needs of multilib systems. It's no longer a good idea
18     # to assume all libraries will end up in lib. Replace any (sane) instances
19     # where lib is named directly with $(get_libdir) if possible.
