Hi Wolfgang, I had a good compile of 6.0.1 from Thursday's cvs on Mac OS X 10.2.6. I did a stage 2 build using your 6.0 package, then installed 6.0.1 and rebuilt everything. I ran but a few test programs (mostly some networking stuff I've been playing with); superficially it all works. A minor issue: ghc advertises itself as version 6.1, ghci as 6.0.1. Which is correct? Best Wishes, Greg
