Custom modules do not load at first (Python)

I installed Pandas version 0.12.0 on the site and the user needs 0.13.0. I told him to install it in his home directory, which he made, but when he types import pandas, he finds the old module.

So, I decided to print it out sys.pathand noticed these paths in that order (others were deleted to save this message):

[
    '',
    '/apps/python/2.7.5/lib/python2.7/site-packages/pandas-0.12.0-py2.7-linux-x86_64.egg',
    '/home/user/.local/lib/python2.7/site-packages',
    '/apps/python/2.7.5/lib/python2.7/site-packages'

]

PYTHONPATH appears after Pandas:

[
    '',
    '/apps/python/2.7.5/lib/python2.7/site-packages/pandas-0.12.0-py2.7-linux-x86_64.egg',
    '/usr/lib64', // this is the PYTHONPATH
    '/home/user/.local/lib/python2.7/site-packages',
    '/apps/python/2.7.5/lib/python2.7/site-packages'

]

What could lead to the fact that pandas -0.12.0 will be specially loaded first of all, even PYTHONPATH? There are several other packages that also exhibit the same behavior. All packages are installed pipor running python setup.py install; can any of the methods cause such a problem? I do not think that we edited something manually.
