One relatively new feature in SBCL is the ability to make executable images in a fairly straightforward manner: simply pass :executable t to sb-ext:save-lisp-and-die, and the system will attempt to dump one file that plays relatively nice with the executable loader on your given system. Since it is fair to say that there are a large number of dependencies in McCLIM, and additionally a non-dependency that is in practice needed to get windows to display on the screen, it seemed reasonable to use this executable-generating functionality to distribute a binary that could be tried out before deciding whether or not to get the source to a fair number of software projects.
So, Andreas Fuchs duly stepped up to build a binary of mcclim-0.9.2 for x86/linux, and all seemed well. However, I remembered that some people had expressed an interest in a Mac OS X binary, so I went about building one of those[*]. And all seemed well; a few things had to be changed from Andreas' binary, mostly because SBCL on x86/linux supports threading, while on ppc/darwin it has to make do with select(). However, trying the binary revealed some odd things going on: using Apple's X11.app, you would need to hit RET twice to get your input accepted: only not quite systematically: also, sometimes, the REPL's answer would only appear after a subsequent keystroke.
Amusingly, the same behaviour was far less systematic when running the same binary over an ssh-forwarded connection to an xorg server. This is perhaps not overly surprising, but it did make debugging the problem, or even identifying the proximate cause, a lot harder. Tim Moore and Juho Snellman did end up tracking it down, though: Tim worked out that read-char-no-hang was hanging, and Juho spotted an error in a recent bugfix in SBCL for listen: sometimes the system would report that data was available on a socket even when it wasn't. The difference in behaviour of the buggy binary between X servers is I think explained by a difference in double-buffering: Apple's windows are double buffered, so they never receive any Expose events, whereas xorg's aren't, and so they receive many more events in total; and a failure to respond in a timely manner to an Expose event is less noticeable than not doing anything when hitting the Return key...
The upshot is that SBCL 0.9.11 is unfortunately unsuitable for McCLIM work; however, armed with a hotfix for listen, I have made available an OS X binary of mcclim 0.9.2 for people to try: you'll need X to be running, and also to have libfreetype.dylib in /usr/X11R6/lib/.
[*] For the record, the build script ended looking like this for OS X:
