 Sorry, been away from PPC hardware until now, gonna return to this soon.
 Thank you for the portfile, it is perhaps a better solution that what I
 had in May, where I used an extra port to bootstrap SBCL first.

 By the way, threads are still broken, right? There was [at least] one part
 in PPC assembler which lacked Darwin version.
