I've tried Strawberry, which I like a lot. Installation is simple and many modules are already included. Ultimately I need to install BioPerl and so far I've been unable to get that to work under Strawberry. So, I've reverted to ActiveState. The BioPerl site has very clear instructions for installation under ActiveState however I ran into the problem that I described in my original post. I'd prefer to work with Strawberry...there's a beta of Strawberry which includes BioPerl so I may have to go with that. Thanks!
