pylint #76910 pip install errors/warnings [validation pending]

I get these errors in console when I install pylint on python 2.7 with pip.
Installation succeeds though.
It looks like these are test cases and the they are designed to through errors and warnings, in which case could these be wrapped in setup.py not to spew the text on the console?
