Like said before use the right version of perl for the modules.

When using activestate use ppm , this is a nice tool for installing packages.

But I like dynamicstate more. Because of the fact you can install from activestate, dynamicstate and from cpan all with a som clicking in a browser!!! It does this all nicely even installing/compiling from cpan.
On a side-note it also has a apache with cgi to test your scripts in it's distribution.
Check it out. Try them both an read the docs coming with them!
