HI, For darwinports users on Mac OS X who just have to live on the bleeding edge, a new port of the development version of GHC is available. It builds from the latest cvs. (So you take your chances. There's no guarantee that the build process will work, not trash your machine, not render your city a smoking, radiating ruin or change the signature of the spacetime metric. Although the last two are believed unlikely.) The executables all have the suffix -6.5, so you can install along with your regular ghc without conflict. For more information on darwinports, see http://darwinports.opendarwin.org Best Wishes, Greg Gregory Wright
