hi,

i've installed EPD 6.3 x64 on an ubuntu machine and then i installed
virtualenvwrapper and pip. i setup a new virtual environment and
easy_install nibabel. if i launch ipython, it invokes the correct ipython
from EPD but i cannot import nibabel. if i simply launch python, i can
import nibabel.

this is sys.path from ipython launched within the virtual environment

['',
 '/software/python/EPD/6.3/bin',
 '/software/python/EPD/6.3/lib/python2.6/site-packages/virtualenvwrapper-2.6.1-py2.6.egg',
 '/software/python/EPD/6.3/lib/python2.6/site-packages/virtualenv-1.5.1-py2.6.egg',
 '/software/python/EPD/6.3/lib/python26.zip',
 '/software/python/EPD/6.3/lib/python2.6',
 '/software/python/EPD/6.3/lib/python2.6/plat-linux2',

 '/software/python/EPD/6.3/lib/python2.6/site-packages/IPython/Extensions',
 u'/users/satra/.ipython']


this is sys.path from python launched within the virtual environment

------------

any ideas as to why ipython is not being loaded with an updated sys.path?

cheers,
