Ok,
If Perl is configured OK, mod_perl gets the args from Perl and
everytning goes well, the same on all normal Makefile.PL building
modules.
But you must take care that the rests of things you had to use are
compiled also with -fPIC.
All RedHat or Fedora default builds seems to have been compiled that
way, so no problems for default libs.
