Don't import vars from setup.py

[amercader]

When using setuptools>=19.4 installation fails with an exception:

Traceback (most recent call last):

  File "<string>", line 17, in <module>

  File "/home/adria/dev/pyenvs/fiware/src/ckanext-oauth2/setup.py", line 25, in <module>

    from ckanext.oauth2 import __version__, __description__

  File "ckanext/__init__.py", line 23, in <module>

    pkg_resources.declare_namespace(__name__)

  File "/home/adria/dev/pyenvs/fiware/local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2229, in declare_namespace

    _handle_ns(packageName, path_item)

  File "/home/adria/dev/pyenvs/fiware/local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2198, in _handle_ns

    path.sort(key=sort_key)

  File "/home/adria/dev/pyenvs/fiware/local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2196, in sort_key

    return sys_path.index(_normalize_cached(os.sep.join(parts)))

ValueError: '/home/adria/dev/pyenvs/fiware/src/ckanext-oauth2' is not in list

This seems to be related with this setuptools issue:

In any case, it can be avoided removing the imports from setup.py

This bug is solved in setuptools 19.6.2. Anyway, I cannot reproduce the problem. I have installed several versions of setuptools and the installation process (python setup.py install) is working in all of them. Do you still have the same problem?
