Eclipse is a good open-source IDE w/ wide range of programming languages, all developed and supported by community.
Especially, for a Perl IDE, I suggest you just need to stick with Eclipse and add the Perl Editor plugin. That's all! You'll have a greate Perl IDE, from editor including grammar check, syntax highlight, built-in interpretation.
Moreover, it's easier for you to organize a project.

It's worth of use and great!
Have fun!@
