|

| 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 | #
|
