1) How about only installing TT (Template Toolkit) in the clients (i.e. just the PCs of your techs)? If that would be ok, you would have a script on the server that just collects and sends the data and a script on the client that formats that with TT

2) Or put up a little web server on your machine and let the techs look at that (with basic authentication). Your script would get the data the same way as above but TT would only be installed on your machine

3) Text::Template seems to be without dependancies (you can find out these things simply through searching for 'template' in CPAN and a few more clicks, by the way). You could (instead of installing it), simply include the source of Text::Template into your script. Your script would be a little larger than intended but still in one piece and working on vanilla perl
