Thanks Corion.
Actually I wasn't using the Tagset.pm. I encountered it while installing libwww-perl-5.808.tar.gz and it complained it couldn't find Tagset. I used find . -name "Tagset*" and got

./lib/perl5/site_perl/5.8.8/i486-linux-thread-multi/auto/HTML/Tagset
./lib/perl5/site_perl/5.8.8/HTML/Tagset.pm

The first line referred to an empty directory. I'm not sure if this is a bug. If someone thinks it is a bug, perhaps they could report it.
Thanks again.
