I tried this out last week. Eclipse is a pretty hefty download, 67 MB, IIRC. It's a lot more generally polished and advanced than Komodo, although I admit I haven't tried Komodo in the last six months or so. It did take a bit of configuration in order to get working, for instance, one might have expected it to say, detect your perl installation automatically (or at least one of them). I couldn't get the regex editor working but didn't try very hard so it's probably just me. Depending on the size of your perl scripts, using an IDE like this might be overkill. The editor seems like it would be a better match for a large object-oriented software development project. In any case, this is not intended to be a negative, I had a positive experience using EPIC.
