I also use Gnu Emacs with cperl-mode (under Win32, Solaris and Linux) and a slightly adapted version (due to my taste and some OS-differences) of Steve Ackermann's .emacs which gives me easy access to emacs features like dos<->unix converting, a little filebrowser, commenting and identing of regions, ...

Some time ago, I had a look at Kommodo from http://www.activestate.com/, and nearly liked it as much as emacs especially because of the debugger. But I hardly ever have to debug my codes with a debugger; most often, some prints are faster.
