Hello,
During the last few weeks, I have seen lots of people stumble over the slime-1.2.1 tarball, and having it not work. I think this is a pitty.
If nobody wants to engineer regular releases, it would be already a *lot* better to just substitute the slime-1.2.1 with weekly snapshots.
If you want I can set up the snapshot scripts and update the web page, although I would have to be added to the slime group at common-lisp.net.
Regards,
Mario.
