It gives error when symlinked python command (from virtualenv) is used

symlink_python_command_error.sh

$ virtualenv venv
# Symlink virtualenv bin/ to bin on current directory
$ ln -s venv/bin/ bin
# Run python from symlinked 
$ bin/python 

# Inside Python shell
$ >>> import datetime
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named datetime

# But this works with Python installed via brew
$ ln -s /usr/local/bin/ bin
$ bin/python
>>> import datetime

Ok, it's because of path. Python updates sys.path according to current directory of interpreter, and doesn't work with symlink https://groups.google.com/forum/#!topic/python-virtualenv/rjJ4aYXrTDs
