How about making the "not linked with libperl.so.x.y" warning non-fatal
then? Right now I cannot just ignore it as suggested because it makes
the script exit with a non-zero error code.

While here: there's a FIXME comment in this part that talks about
changing the linkage detection logic, but it does not specify what
should be changed. Do you have more information? I could try to fix both
issues and send a patch for review.
