Hi, I'm having problems installing the OS X bindist of GHC 7.8.3 on my machine. Here are the specs for my machine: Hardware: MacBook Pro, 13-inch, Mid 2009 Operating System: OS X 10.8.5 gcc: i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00) Note that I only have the Xcode 4 CLI tools installed, not Xcode 4 itself. The line that fails is:

/usr/bin/gcc -E -m64 -undef -traditional -Wno-invalid-pp-token -Wno-unicode -Wno-trigraphs -P -DINSTALLING -DLIB_DIR='"/opt/ghc/7.8.3/lib/ghc-7.8.3"' -DINCLUDE_DIR='"/opt/ghc/7.8.3/lib/ghc-7.8.3/include"' -DPAPI_INCLUDE_DIR="" -DPAPI_LIB_DIR="" -DFFI_INCLUDE_DIR= -DFFI_LIB_DIR= '-DFFI_LIB="Cffi"' -x c -Iincludes -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist-ghcconstants/header rts/package.conf.in -o rts/dist/package.conf.install.raw cc1: error: unrecognized command line option "-Wno-invalid-pp-token" cc1: error: unrecognized command line option "-Wno-unicode" make[2]: *** [rts/dist/package.conf.install] Error 1 make[1]: *** [install] Error 2 make: *** [install] Error 2

Earlier in the configuration process I see:

checking XCode version... xcode-select: Error: No Xcode is selected. Use xcode-select -switch <path-to-xcode>, or see the xcode-select manpage (man xcode-select) for further information. not found (too old?)

Could that be the culprit? The entire installation log can be found here: https://gist.github.com/christiaanb/ec06e93fa16fdfdb5fa3 -- Christiaan
