Comment (by kakuhen):

 I attempted to build SBCL 2.2.2 from SBCL 1.0.47 within a Portfile. Here
 are my observations.

 > {{{
 > unhandled SIMPLE-ERROR: make-host-1 stopped due to unexpected STYLE-
 WARNING.
 > }}}

 Enabling the debugger will stop the error from happening, but MacPorts
 does not offer a way to interactively select a restart, or
 programmatically select a restart. The problematic code comes from
 src/code/class.lisp L1285-1358. The STYLE-WARNING is signalled with
 message "IGNORABLE declaration for an unknown variable: TRANS-P."

 **Note**: My own copy of SBCL 2.2.2 does not signal the STYLE-WARNING when
 compiling SBCL. This is properly an SBCL 1.0.47 issue.

 Another note: my non-MacPorts SBCL 2.2.2 build succeeded because I was
 compiling SBCL without the --fancy argument. This explains why I did not
 run into issues with threads. More concretely, here are the entries in
 *FEATURES*.

 {{{

  :PACKAGE-LOCAL-NICKNAMES :SB-LDB :SB-PACKAGE-LOCKS :SB-UNICODE :SBCL

 }}}

 With that said, I have uploaded a Portfile that I am experimenting with.
 Everything is done on Mac OS X 10.5.8.
