in reply to A good editor for Perl sources
I've been using Eclipse with the EPIC plugin on Windows (various), Linux (various) and lately Mac OSX. It has served me well over the years and behaves almost identical on all platforms (the Mac being the exception...). It has tons of features and some very useful plugins.
If you don't mind spending money you might give the komodo a try. I have only played with the free trial but it looked good.
Cheers
