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.

24 # Added support for ${ABI} and ${DEFAULT_ABI}. If they're both not set,
25 # fall back on old behavior. Any profile that has these set should also
26 # depend on a newer version of portage (not yet released) which uses these
27 # over CONF_LIBDIR in econf, dolib, etc...
