Installing in a python 3.3b2 or python 3.3rc1 virtual environment.

[andrewspiers]

Hi, I'm having trouble installing inside a venv.

I activate the venv, install distribute, install ipython:
python setup.py install
and then when trying to run the ipython3 binary which is installed, I get
'TypeError: init() got an unexpected keyword argument 'version'
Have I perhaps missed some necessary dependency?

Traceback is given below. I've tried the git version of ipython, and
ipython 0.13.

(ipythontest) andrew@wiki:~/ipythontest/bin$ ./ipython3

Matthias Bussonnier suggests:
"version" keyword seem to be deprecated even in 2.7, it might have been dropped in the version of python you use, so it a bug on our side.

http://hg.python.org/cpython/file/2.7/Lib/argparse.py
1557 if version is not None:
1558 import warnings
1559 warnings.warn(
1560 """The "version" argument to ArgumentParser is deprecated. """
1561 """Please use """
1562 """"add_argument(..., action='version', version="N", ...)" """
1563 """instead""", DeprecationWarning)

Background:
I'm running Debian squeeze, I installed the dependencies listed in the
debian .dsc file for python 3 before doing a source install. That is,
the following packages:
quilt autoconf libreadline6-dev libncursesw5-dev zlib1g-dev
libdb4.8-dev tk8.5-dev blt-dev libssl-dev sharutils libbz2-dev
libbluetooth-dev locales libsqlite3-dev libffi-dev mime-support
libgpm2 netbase lsb-release bzip2 gdb

This seems to fix it:

I believe this was fixed in #2345.
