Note (probably harmless): No library found for -ltidy

It seems that you don't have libtidy installed.  HTML::Tidy does no
real work on its own.  See the section "INSTALLING LIBTIDY" in Tidy.pm
for a step-by-step walkthrough of building the lib.  You can also refer
to http://tidy.sourceforge.net/.

If you do have libtidy installed, and I just haven't detected it,
go ahead and try building.  If HTML::Tidy builds and tests correctly,
then please let Andy Lester know at bug-html-tidy@rt.cpan.org so that
he can fix the library detection code.

Checking if your kit is complete...
Looks good
