Well, unfortunately, I haven't been able to get it to install successfully. Several errors having to do with io, haskell, etc. I posted the error messages I got when it was going through the make test process on a mac perl list and as of now, there hasn't been any responses. So, it looks like I'm going to have to wait for Pugs to be a bit more mature before trying again (and meanwhile, if there's anyone in here who's been able to successfully get Pugs installed in their OS X system, I'd love to learn your secrets!).
