setup.py shouldn't have requires

[Ionuț Arțăriși]

Hi,

We're currently getting the following error from glanceclient on SUSE:

# glance help
Traceback (most recent call last):
  File "/usr/bin/glance", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib64/python2.6/site-packages/pkg_resources.py", line 2739, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib64/python2.6/site-packages/pkg_resources.py", line 588, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: python-keystoneclient>=0.1,<0.2

I noticed that python-glanceclient's setup.py file explicitly sets the version of install_requires. For all the other components, the requirements aren't enforced in setup.py and I don't think glanceclient should be a special case. Specifying the unversioned requirements or simply leaving them out of the setup.py is a better solution. Pip can still find them in the pip-requires file of-course and that's what most scripts use anyway.

This isn't good for downstream distributions (such as us) who do their own packaging and take care of the dependencies themselves.

If I 'pip install python-glanceclient' I expect it to work - that means all required dependencies are installed. I'm not setting requirements to specific version for fun here, there's always a reason.

It also appears that you're mixing packages and pip for installing software. That will definitely cause problems for you.
