46# This function simply returns the desired lib directory. With portage
47# 2.0.51, we now have support for installing libraries to lib32/lib64
48# to accomidate the needs of multilib systems. It's no longer a good idea
49# to assume all libraries will end up in lib. Replace any (sane) instances
50# where lib is named directly with $(get_libdir) if possible.
