Python3 setup.py install failiure

I have problems running python3 setup.py build on the latest git head using ubuntu 11.10.

2to3 fails with errors like:
Can't parse docstring in build/lib/IPython/core/usage.py line 195: ParseError: bad input: type=1, value='arg1', context=(' ', (195, 12))

This happens because of to different issues:
In IPython/parallel/client/view.py there is an unbalanced (

In IPython/core/usage.py the automagic docstrings are not valid python code (Thats the point I guess)
To fix this I changed the prompts from regular python prompts to ipython ones. But I guess the right fix should be to have 2to3 skip the parsing on these strings.

Odd, I'm building it semi regularly with Ubuntu 11.10, and I haven't had any problems.

OK, apparently it works differently outside a virtualenv for some reason. Not sure why, maybe it's a different version of distribute.

Anyway, these changes looks sensible. Thanks.

I don't see a problem here, but @takluyver is our resident py3 expert, so I'd like to leave the final call on this one up to him. But as far as I can tell, it's good to go, thanks! (though as a note, I did test python3 setup.py build on ubuntu 11.10 just now, and didn't see any errors; but further cleanups won't hurt in any case).

Merged - thanks, Jens.

@fperez: It seems it works in a virtualenv, but not outside (at least for me). Maybe different versions of distribute are getting imported. Anyway, the changes make sense and don't break the test suite.

Weird: I wasn't running in a virtualenv, just running 'in plain sight' :) But in any case, I agree with you; I just wanted your OK on it given the py3 focus. Thanks!
