Hi, I have written a module for use with freeRADIUS which seems to work fine and dandy on my desktop Fedora box. However when I drop this module and config on one of the production (and now test) Debian Sarge boxes running the same initial config with same version of freeRADIUS I get : /usr/sbin/freeradius: relocation error: /usr/lib/perl5/auto/DBI/ DBI.so: undefined symbol: Perl_Gthr_key_ptr and freeRADIUS obvioulsy refuses to start. I have googled this and it seems to be a fairly common error with perl, alas I cannot see anything to help resolve this, so I am asking here in the hope that someone else may have thwarted this pain. I have checked and perl supports multi and threaded .. libperl-dev did not sort it .. any other suggestions ? please ? :) (that don't involve installing Fedora on there.. tho that is getting more and more tempting) Graeme
