 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

This happened on a Fedora system, which had the bmap-tools package installed,
and where I tried to update the python package.

The RPM build logs had this:
Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PartialHardlinkSets) <= 4.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1
Requires: /bin/python python(abi) = 2.7

So there was a "/bin/python" requirement.

The theory is that "python.x86_64 0:2.7.5-9.fc20" had "Provides: /bin/python",
but this line was removed in "python.x86_64 0:2.7.5-11.fc20". But I did not
check this theory.

And the other theory is that rpm build picks "/bin/python" instead of
"/usr/bin/python" simply because "/bin" goes first in the PATH environment
variable in the build root environment.

Fedora says that the right way to call 'setpu.py' is

%{__python} setup.py

see https://fedoraproject.org/wiki/Packaging:Python,
and this is what this patch does.
