Installing ghc-7.8.3 OS X bindist fails on Xcode 4 CLI-only machine

[Christiaan Baaij]

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

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.

Could that be the culprit?
