Comment (by kakuhen):

 My copy of CCL reports the version "1.7-dev." Maybe I am not remembering
 the correct revision. But this the latest version I was able to compile on
 DarwinPPC64.

 With that said, CCL 1.7-dev does not seem able to compile SBCL 2.2.2.
 Moreover, other lisps (such as the latest version of ECL), seems to
 introduce a bug into SBCL that messes with GET-INTERNAL-RUN-TIME.

 With that said, I was able to compile SBCL 2.2.2 using 1.0.47 on **Mac OS
 X Leopard**. It does not seem to work on **Mac OS X Tiger**, based on the
 discussion above. So on Darwin 9 (ppc), it may be easiest to start the
 compilation process with SBCL 1.0.47. I will try to make a minimal
 Portfile to build SBCL 2.2.2 in this manner soon and report results.
