Ubuntu used to come with a system perl already pre installed, not sure about Ubuntu 23 ... for checking lvalues it's more than enough

Sure, sure. In How do I install a Perl module? he indicated he had perl running on his Ubuntu box and was seeking advice on installing a CPAN graphics module. Unfortunately, he went quiet after that and didn't report back how it all went ... presumably not well if he's back on the dreaded TinyPerl on Windows XP. :)
