Okay.  This is NOT HTML::Parse and Perl will not look at this one to find
HTML::Parse.  This is probably Parse::Yapp which is a Perl extension for
generating and using LALR parses.

To get HTML::Parse you're going to have to install it.  HTML::Parse is a
wrapper around HTML::TreeBuilder.  You can get this by installing the
HTML-Tree-3.18 package.  Although earlier versions are probably
acceptable.  To download this go to it's CPAN page
(http://search.cpan.org/~sburke/HTML-Tree-3.18/) and grab the source, or
go to your favourite linux distribution site and see what package they
have for you.  Alternately you can use the CPAN module:

# perl -MCPAN -e 'install HTML::Tree'

:( 
Well, get yourself a copy of HTML::Tree and its friends and this problem
will be solved.

Thanks for that.  If you allow HTML::Tree to be installed in the place
that Perl picks for it, this should be found automatically.  If you
install HTML::Tree into a local location for whatever reason, then you can
help Perl find the library by modifying the environment (in your script)
before doing this.  IE:

export PERL5LIB=/path/to/local/location/
lwp-request -o text 'http://www.etc

This assumes you have something like:
	/path/to/local/location/HTML/Parse.pm

As far as I can tell it's a bug that LWP is still using HTML::Parse.pm.
It appears that almost everything has been upgraded to use
HTML::TreeBuilder.  It also appears that HTML::TreeBuilder is accidently
omitted from the required modules to install when installing LWP.  I'll be
reporting both of these on your behalf.

Let me know how all the above goes.
