Sbcl builds from the source on the most Unixes at least Just to be clear -- it does *not* build from source using the GCC compiler anywhere. It requires an existing common lisp implementation to get anywhere. The first sentence of guide to installing SBCL from source says: "To build SBCL you need a working toolchain and a Common Lisp system (see section 2.5 "Supported platforms")." As a result, SBCL can't be used for Sage, as mentioned above. I should also mention that according to http://sbcl.sourceforge.net/platform-table.html, SBCL doesn't support Microsoft Windows. > > >> Why do you think cmucl or sbcl would give high performance.

It's a really good idea to try the same code on top of clisp, sbcl, or whatever, if you have the time.
