Demo of my problem with the test suite:

$ ./python -m test.regrtest
Traceback (most recent call last):
  [. . .]
  File "/media/disk/home/proj/python/cpython/Lib/test/test_support.py", line 1423, in check_impl_detail
    return guards.get(platform.python_implementation().lower(), default)
  File "/media/disk/home/proj/python/cpython/Lib/platform.py", line 1451, in python_implementation
    return _sys_version()[0]
  File "/media/disk/home/proj/python/cpython/Lib/platform.py", line 1416, in _sys_version
    repr(sys_version))
ValueError: failed to parse CPython sys.version: '2.7.11+ (qbase qtip subprocess-stderr_redirect_with_no_stdout_redirect-2.diff tip:0b64128) \n[GCC 5.3.0]'
