Dynamic linking on Mac

Many dynamic libraries refer to the build tree.

(1) Every ".dylib" installed with GHC head refers to itself in its build directory. E.g.

% otool -L libHSbase-4.7.0.0-ghc7.7.20130909.dylib | grep base
libHSbase-4.7.0.0-ghc7.7.20130909.dylib:
	/Users/kazu/work/ghc/libraries/base/dist-install/build/libHSbase-4.7.0.0-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)

(2) Some ".dylib" installed with GHC head refers to other libraries in their build directories. E.g.

% otool -L libHSvector-0.9.1-ghc7.7.20130909.dylib | grep /Users
	/Users/kazu/work/ghc/libraries/vector/dist-install/build/libHSvector-0.9.1-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)
	/Users/kazu/work/ghc/libraries/primitive/dist-install/build/libHSprimitive-0.4.0.1-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)

(3) All user installed libraries by cabal-install refer to other libraries in their build directories. E.g.

% otool -L libHSghc-paths-0.1.0.9-ghc7.7.20130909.dylib| grep Users
	/Users/kazu/Library/Haskell/ghc-7.7.20130909/lib/ghc-paths-0.1.0.9/lib/libHSghc-paths-0.1.0.9-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)
	/Users/kazu/work/ghc/libraries/base/dist-install/build/libHSbase-4.7.0.0-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)
	/Users/kazu/work/ghc/libraries/integer-gmp/dist-install/build/libHSinteger-gmp-0.5.1.0-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)
	/Users/kazu/work/ghc/libraries/ghc-prim/dist-install/build/libHSghc-prim-0.3.1.0-ghc7.7.20130909.dylib (compatibility version 0.0.0, current version 0.0.0)
