LINKFORSHARED incorrectly returns a truncated value by default, which breaks builds which depend on it returning a valid path. e.g., it returns: Python.framework/Versions/2.7/Python Instead of: $(brew --prefix)/Python.framework/Versions/2.7/Python This breaks zpython, and possibly other things. See Homebrew/homebrew#20182. Reported to Python.org in http://bugs.python.org/issue3588 and http://bugs.python.org/issue16848, fixed for python-config but not other usecases.
