We're in the process of clearing out the dry-rot from a previous port of CLM to the SGI in ACL, and I hope to have it running very soon (especially since I recently bought an SGI). CMN runs ok, I think (in ACL 4.2). As soon as CMUCL (or GCL?) are running on the SGI, I'll tackle porting to them. I'll send cmdist a note when this is in a usable state.
