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

#   fall back on old behavior.  Any profile that has these set should also
#   depend on a newer version of portage (not yet released) which uses these
#   over CONF_LIBDIR in econf, dolib, etc...
