What does "error: option --single-version-externally-managed not recognized" indicate?

I seem to have suddenly started encounter the error error: option --single-version-externally-managed not recognized when pip installing varions packages (including PyObjC and astropy). I've never seen this error before, but it's now also showing up on travis-ci builds for which nothing has changed.

Does this error indicate an out of date distribute? Or some incorrectly specified option in setup.py? Or something else entirely?

pip install --egg SCons
