Package "numpy" at version 1.10.0.post2 has a version discrepancy. Looking in PKG_INFO, we clearly see:

Version: 1.10.0.post2

But when querying the pypi API as such:

curl https://pypi.python.org/pypi/numpy/json/

We find the version represented as simply "1.10.0":

        "1.10.0": [
            {
                "has_sig": true, 
                "upload_time": "2015-10-07T19:47:09", 
                "comment_text": "", 
                "python_version": "source", 
                "url": "https://pypi.python.org/packages/source/n/numpy/numpy-1.10.0.post2.tar.gz", 
                "md5_digest": "5594d8c5c006db8901fca585a29f3620", 
                "downloads": 53995, 
                "filename": "numpy-1.10.0.post2.tar.gz", 
                "packagetype": "sdist", 
                "size": 4082399
            }, 

During a sync, this makes it difficult to know if pulp already has that package. It appears the only option is to actually download it and inspect it, unless we are comfortable ripping the version out of the filename. For now, I will proceed with downloading the package, and handling the possibility that a NotUniqueError will be raised when saving.
