In my experience, the most common reasons that Perl code would require a version 
over 5.8 is due to wanting to use some new syntactic features such as that, and 
that instead sticking to the syntax 5.8 has would not change the code very much.

There are other, deeper features of Perl versions over 5.8 that make them worth 
upgrading to, but often code incompatibilities aren't due to people needing 
these things, and so for that code it should still support 5.8.

Bottom line, if a Perl module/script you depend on requires a higher Perl 
version number than you have, don't just take that at face value but look into 
it and you may often find that tweaking this module's source is indeed the 
easiest path.
