| 8 | # - shared libperl support is tricky. if ever libperl.a ends up |
| 9 | # in /usr/local/lib/* it can override any subsequent builds of |
| 10 | # that same perl release. to make sure you know where the shared |
| 11 | # libperl.a is coming from do a 'dump -Hv perl' and check all the |
| 12 | # library search paths in the loader header. |
| 13 | # |
| 14 | # it would be nice to warn the user if a libperl.a exists that is |
| 15 | # going to override the current build, but that would be complex. |
| 16 | # |
| 17 | # better yet, a solid fix for this situation should be developed. |
