|The stupid question is the question not asked|
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!
My opinions may have changed,
but not the fact that I am right
