Hi, Due to overwhelming popular demand (well, Sven asked), darwinports now includes a port 'lang/ghc-devel', which builds from the head of the cvs. The default build includes support for openGL, so this is a way to get the latest OpenGL support for ghc, which now supports almost all of version 1.5. The ghc-devel port installs as ghc-6.3. (All of the executables have the "-6.3" suffix, so you can install ghc and ghc-devel without conflict. You invoke the new compiler as ghc-6.3 and the interactive environment as ghci-6.3.) ghc-devel depends on ghc, alex and happy, so if you have none of these installed and say sudo port install ghc-devel you'll get a full bootstrap build of the released version of ghc, along with builds of alex and happy (the lexer and parser generators, respectively), followed by a build of ghc from cvs. This may take some time (about 10 hours on an 800 MHz G4), but what would you rather have your CPU doing?
