I tried to run some tests from  the python3.4 test suite and got:
python3 -m test -ugui test_tk test_ttk_guionly test_idle
/usr/bin/python3: Error while finding spec for 'test.__main__' (<class 'ImportError'>: bad magic number in 'test': b'\x03\xf3\r\n'); 'test' is a package and cannot be directly executed

The actual problem has nothing to do with test being a package.  It
had to do with finding a python2 pyc and trying to run that.  It would be nice if the patch checked for this problem as well before concluding that somebody just tried to execute a package.
