The new Mac OS X 10.2 has arrived, and GHC has stopped working. I've compiled a new GHC binary that runs on 10.2 (but not anymore on 10.1). It is available at: http://www.uni-graz.at/imawww/haskell/JaguarGHC.tar.gz This archive contains just a new GHC binary, the rest of the binary release already has to be already installed. What happened: With Mac OS X 10.1, Apple had included a 'curses' library in it's main 'libSystem.dylib' library. For 10.2, they removed that, and instead added a separate ncurses library (which wasn't included in 10.1.). GHC relies on one of those libraries (via readline), but readline has to be recompiled to use the other library. GHC-compiled programs that don't explicitly link against readline are not affected by this problem. Cheers, Wolfgang
