I finally got MP3::Info out, version 0.90. Not 15 minutes after it went out -- after the previous version has been out for over 10 months -- dynweb gives me a bug report (a warning isn't being caught for files of size 0). Figures.
I got a lot done on MacPerl over the past few days. I am going to do a build from scratch, hopefully tomorrow, maybe on the iBook or iMac. Then I can finish up the build instructions, and do an alpha source release.
