Title: FIX: fix error for setup.py for Python 3

The subprocess command in Python 3 returns a bytes object. If the homebrew
subprocess check returns a not-empty result, then setup crashes trying to
combine the bytes with the string constants with and error like "TypeError:
Can't mix strings and bytes in path components."
