[Twisted-web] Fwd: Troubles installing 11.1.0 - is this expected?

python -m easy_install is just a way to use easy_install as a library,
instead of invoking the easy_install shell command (which is problematic,
since on some machines I have up to 4 different versions of Python: 2.6,
2.7, PyPy, Jython).

if I use easy_install directly, I get the exact same error:

sudo easy_install -U Twisted

Will file a ticket for both
