Dear Tiger Mac-users, binary distributions of GHC 6.8.1 for Mac OS X 10.4 (Tiger) are stored at: http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... and http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... As for ghc-6.6.1 both distributions rely on (the "universal") GMP and GNUreadline frameworks found at: http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... instructions at: http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... The ppc distribution features the bug: http://hackage.haskell.org/trac/ghc/ticket/1845 Only HADDOCK documentation is included. (The message at the end of an installation is wrong anyway, because a wrong directory is tested: Warning: this binary distribution does NOT contain documentation!) I haven't checked the installation against a test-suite (could someone put one up for download?), but the distributions work for our purposes and might be useful for you, too. Christian
