Description of problem:

Python 3.4's entire ssl module was backported to 2.7.9 [1].  Setuptools already has a try/except statement to import CertificateError and match_hostname from the standard library ssl module if they are available [2].  Effectively, the rpm has a dependency that isn't being used.  Because of that, I believe that these lines should be removed from the python-setuptools spec file [2].

-Requires:       python-backports-ssl_match_hostname
-BuildRequires:  python-backports-ssl_match_hostname

Version-Release number of selected component (if applicable):

python-setuptools-12.0.3-1.fc22.noarch

How reproducible:

$ # CertificateError in the standard library
$ grep 'class CertificateError' /usr/lib64/python2.7/ssl.py
class CertificateError(ValueError):

$ # match_hostname in the standard library
$ grep 'def match_hostname' /usr/lib64/python2.7/ssl.py
def match_hostname(cert, hostname):

$ # setuptools tries to import from the standard library first [3]
$ grep -B1 -A7 'from ssl' /usr/lib/python2.7/site-packages/setuptools/ssl_support.py
try:
    from ssl import CertificateError, match_hostname
except ImportError:
    try:
        from backports.ssl_match_hostname import CertificateError
        from backports.ssl_match_hostname import match_hostname
    except ImportError:
        CertificateError = None
        match_hostname = None

Actual results:

The RPM has a dependency that it isn't using.

Expected results:

The RPM only depends on things it actually needs.
