HTML::Tagset can be downloaded form CPAN.

I'm updating to give an error if HTML::Tagset is not installed.

It's a good idea to also upgrade the libwww-perl library (LWP) as current
versions of LWP support Keep Alives, and the program can use this
feature to make spidering faster and to reduce the load on the web server.

The LWP modules are ones to really keep on top of, as they are being
upgraded often to keep up with protocols and the collection of things that
LWP has to properly connect to.  I would not expect venders (such as Sun,
or Linux distributions) to be on top of this; just install from CPAN.
