You might take a quick look at t-pad on CPAN. It's fairly light weight Perl editor (written in Perl that is) with Perl colour syntax highlighting. I've not used it much at all, I happened upon it yesterday when I was pokint around that corner of CPAN.

If you are prepared to spend a small amount of money I'd second the motion for Komodo. It has a pretty good editor with colour syntax highlighting (and much more), but no spelling checking. It has rather nice project management and snippet handling.
