It took 40 minutes on this K6-233 Karl> 128MB Linux 2.0.35 machine. :-) It isn't impossible because you built the same version from the sources of the version you already had. Try changing some of the internals and building a new version. This is nearly impossible, and just barely possible if you're a CMUCL wizard. If you succeed in this, try porting CMUCL to a new architecture. :-) 40 minutes sounds about right to rebuild CMUCL. On my Gateway PII-300 at work, it takes 10-15 minutes. Ray
