Hello, A port of ghc-6.2 for Mac OS X (both Jaguar and Panther) is available from the darwinports system. Information on obtaining darwinports is available from http://darwinports.opendarwin.org. Once darwinports is installed, building ghc is done by changing to the lang/ghc directory and issuing the command: sudo port install ghc will be built from source and by default is installed in /opt/local/bin, although the user may specify another installation directory. This release supports building with HOpenGL support. It is not included by default, but may be specified by the command: sudo port install +opengl Note that as the system is built from source it may take several hours for the 'port install' command to finish. (On an 800 MHz G4 powerbook it takes about four and a half hours.) ghc from darwinports may be helpful for those still using Jaguar and are having difficulty with Wolfgang Thaller's binary distribution for Panther. Or you may just like building from source, like me. Best Wishes, Greg Wright Gregory Wright Antiope Associates LLC 18 Clay Street Fair Haven, New Jersey 07704 gwright@antiope.com
