Seconded. LWP is a very standard module, so in that example there's really no reason to go on reinventing any wheels. Particularly since most of the modules I use, at least, are very standard and well-known indeed--off the top of my head, the modules I find myself using most often are CGI, LWP, DBI, and XML::Parser. Pretty standard, all.

As for you saying that you have difficulties "getting" modules--what do you mean, exactly? You mean in terms of getting sysadmins to install the modules? Have you thought about setting up your own module area (that you'd own and control), then installing modules into that? The whole module installation thing is really quite easy with the CPAN module.

Just some thoughts.
