#
|
|
# - 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.
