Well, I got PerlQt working on OSX. (screenshot)
It works great, and the recent KDE speedups make a noticable difference over the marginally-working PerlQt I had before. It's as snappy as it can be without more XFree86 speedups.
I just wish we could get over this #&$*@# problem with libartsmidi and friends, and I'd be basically prepared for release. All that would be left is waiting for 3.1 rc6 to come out, with the security audit done, and I'm golden!
