Dear Intel Mac Users, I've also created a binary distribution of GHC 6.8.1 for Mac OS X 10.4 (Tiger) that is based on gmp3 and readline5 libraries under /opt/local/ (without framework dependencies). You can set the DYLD_LIBRARY_PATH if your gmp3 and readline5 libraries are elsewhere. http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... Christian I wonder if that distribution would run under Leopard, too.
