 # On Tue 03 Feb 2004 split off from aix.sh by H.Merijn Brand
 # AIX 3.x.x hints thanks to Wayne Scott <wscott@ichips.intel.com>

 # Notes:
 #
 #    - shared libperl support is tricky. if ever libperl.a ends up
 #      in /usr/local/lib/* it can override any subsequent builds of
 #      that same perl release. to make sure you know where the shared
 #      libperl.a is coming from do a 'dump -Hv perl' and check all the
 #      library search paths in the loader header.
 #
 #      it would be nice to warn the user if a libperl.a exists that is
 #      going to override the current build, but that would be complex.
 #
 #      better yet, a solid fix for this situation should be developed.
