Hi everyone,
Over the last couple of weeks, I have been working on providing lispbuilder-sdl-binaries for OS X which allow people to get up and running without needing a working C compiler. I am happy to announce that these binaries are now available at the following link:
http://code.google.com/p/lispbuilder/downloads/list?can=2&q=mac-lispbuil...
For those of you who want a simple install, just extract these archives over your preexisting lispbuilder-sdl install. (They only contain C binaries, and not the Lisp source code.)
TODO: Make them asdf-installable. Shouldn't be hard, now that they work.
The gory details: See the application-builder mailing list archives.
