I'm seeing the same problem. Of course this had to happen while I was on holiday, so it's something else to sort out as soon as I got back (along with all my real work)!
Can't locate Mysql.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.8.4 /usr/local/share/perl/5.8.4 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .) at test_script line N.
BEGIN failed--compilation aborted at test_script line N.
2) Quick and dirty. This was my first attempt at writing a perl script to do my DB work, and there were lots of basic Mysql samples laying around. I guess maybe this is motivation to move on!
