14 | # Notes: |
15 | # |
16 | # - shared libperl support is tricky. if ever libperl.a ends up |
17 | # in /usr/local/lib/* it can override any subsequent builds of |
18 | # that same perl release. to make sure you know where the shared |
19 | # libperl.a is coming from do a 'dump -Hv perl' and check all the |
20 | # library search paths in the loader header. |
21 | # |
22 | # it would be nice to warn the user if a libperl.a exists that is |
23 | # going to override the current build, but that would be complex. |
24 | # |
25 | # better yet, a solid fix for this situation should be developed. |
