Debian-built perl (installed in /usr/lib/perl5) tries to load DBI module 
from locally built perl (installed in /usr/local/lib/perl). It's a bad 
idea. Try to install debian-built DBI module (libdbi-perl) and use it.

I think the same error (mashup of multiple perl builds) was encountered 
by Johan Meiring.

Debian-built freeradius uses debian-built perl. So only debian-built 
perl modules can be loaded by rlm_perl.

You can easily test your debian-built perl supports loading of DBI (and 
so debian-built freeradius):

/usr/bin/perl -e \
'use DBI; print join("\n", DBI->available_drivers), "\n";'
