  It should generally work.  However... connecting to SQL from the Perl
module is usually a bad idea.  The SQL module already does that.  Why
not use it?

  Try the v3.0.x branch for one.  It has a number of fixes over 3.0.3.

  But you're really asking us to debug *Perl* internals.  FreeRADIUS
isn't failing to load the library.  FreeRADIUS loads Perl, and *Perl*
fails to load the library.  I have no idea how to debug that.
