I installed python3-numpy package, but trying to import it in Python3 interpreter I get this:

$ python3
Python 3.2.3 (default, May  3 2012, 15:54:42) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/zetah/.local/lib/python2.7/site-packages/numpy/__init__.py", line 128, in <module>
    from version import git_revision as __git_revision__
ImportError: No module named version
>>> 

Looking in Synaptic I see python3-numpy is installed in /usr/lib/python3/dist-packages/numpy/

Why is it picking wrong package and what can I do to remedy this?


Update:

OK, in my ~/.profile I have this line:

PYTHONPATH=$PYTHONPATH:$HOME/.local/lib/python2.7/site-packages

but if I remove this line then my Python 2.7 local packages (which I build from source) wont work


Update 2:

Everything seems to work perfect without $PYTHONPATH. I guess it was in my .profile file for nothing
