install active perl dude... and u will get wonderful documentation along with it ... u can easily trigger u r learning using this documentation.
U can download activer perl from somewebsite...(google it).... its a free ware :)
I checked ActivePerl, it promises to make things easy for you, but should you allow them to ? Think about it, if you are going to put yourself a habit of being spoon fed, I believe you are not going to go too far. Rather install the perl interpreter on your own. Write programs in an editor rather than in a fancy IDE, try setting up CPAN modules yourself sometimes, believe me it's not that hard, I've done it. Browse the documentation on your own.
You'll need a few links here they are : http://www.perl.org/ http://perldoc.perl.org/
Edit : There is also a forum dedicated to Perl here post your further questions regarding perl there, I'm sure you will also get a lot of help there.
