[CentOS] Broken package

CentoOS 7 python-cryptography package is at version 0.8.2

It has a build-requires for python-cryptography-vectors of the same 
version (but different source tarball apparently)

There is no python-cryptography-vectors in CentOS 7 base or updates.

There is one in EPEL but it is version 0.8

-=-

If you relax the BuildRequires to just require 
python-cryptography-vectors then the build fails because the build 
script itself checks to see if it is the same version.
