Homebrewed Python 2.7 pip is not working

Question

I installed python 2.7 by using homebrew and updated pip by

easy_install pip
pip install -U pip

After this I was trying to install a python package but I got this error;

pip install pyfasta                                                                           
Traceback (most recent call last):
File "/usr/local/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "build/bdist.macosx-10.9-x86_64/egg/pkg_resources.py", line 2749, in <module>

I appreciate any help on get PIP working.
