dbcheck.pl 0.99 issue with Perl 5.10

Hi

I have to dist-upgrade my XYmon server from Ubuntu 64bits Hardy to Ibex and now, my decheck.pl doesn't work anymore : Tue Dec 30 15:12:34 2008:ERROR on DB01: Timeout connecting to DBI:Oracle:host=oraclesrv01;port=1522;sid=DB01! Tue Dec 30 15:12:34 2008:ERROR on DB02: Timeout connecting to DBI:Oracle:host=oraclesrv02;port=1521;sid=DB02! Tue Dec 30 15:12:34 2008:ERROR on DB03: Timeout connecting to DBI:Oracle:host=oraclesrv03;port=1522;sid=DB03! Tue Dec 30 15:12:34 2008:ERROR on DB04: Timeout connecting to DBI:Oracle:host=oraclesrv01;port=1521;sid=DB04!

Any ideas what could be wrong ?

Thanks by advance!
