Ian Eslick is building a Lisp distribution based on SBCL/ACL with pre-packaged libraries: Think Lisp.

One of the sad consequences of the not entirely irrational bias against lisp in the 80's is that there are no pre-packaged, rich environments that are open source and the commercial packages tend to be too expensive and not widely available at universities that the community desperately needs a platform that one can develop on and distribute as a pre-packaged source of software to allow others to use our research products. I'm building a multi-vendor, multi-platform environment primarily based on SBCL (eventually) for the free version and Allegro for the commercial version due to the excellent compilers that come with them.

The exact list of facilities and utilities that are going to be part of Think Lisp seems to be under consideration.
