You may like to try the E-P-I-C plugin for the Eclipse 3 platform. You can find it over at e-p-i-c.sourceforge.net. EPIC version 0.3.0 has just been released today, the first release designed for Eclipse 3, and it is very cool. In fact, I would say even this early release rivals some of the features of the commercial Perl IDEs I have seen (e.g. ActiveState Komodo).
You owe it to yourself to at least try it out. ;-) I've been keeping an eye on the EPIC project for a while, and I think the combination of the swish new look of Eclipse 3 and the cross-platform nature of Eclipse will make this a must have, especially if you develop in many other laguages as well as Perl.
Updated: I have now had a chance to play around with this a bit more, and the only feature which is still a bit lacking in some areas is the integrated debugger. There are still a few subtle bugs in this which may put a few people off. However there is rich support for external commands, and it shouldn't be hard to add support for another debugger (or even the command line Perl debugger) until the EPIC guys get around to fixing this. Otherwise, I have found this a very nice IDE.
