Problems with non-auto-translated python-2 package variants |

Python-2 variants of python-3 packages that are not automatically
translated by package-with-python2 are not used by auto-translated
python-2 packages.
For example, python2-cryptography requires python2-ipaddress. This is
not required by python-cryptography:
http://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/python.scm#n5838
Python-oauthlib requires python-cryptography, and thus cannot be
translated wholly by package-with-python2. Package-with-python2 fails to
refer to the "hand-made" python2-cryptography that includes
python2-ipaddress, and insteads attempts to generate it automatically.
This results in a failed build of python2-cryptopgraphy because
python2-ipaddress is not being provided. The solution is to remove
python-cryptography from python2-oauthlib and provide
python2-cryptography "by hand":
http://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/python.scm#n2333
This is especially annoying when a python-2 variant needs to refer to
more than one of these "hand-made" python-2 packages:
http://lists.gnu.org/archive/html/guix-devel/2015-12/msg00921.html
There are many python-3 packages that include python-setuptools, even
though they build without it. I assume this is to easily take advantage
of package-with-python2.
Some context:

I’ve pushed the ‘python2-variant’ trick as 1be8334. Subsequent commits
use it for a bunch of packages.
I’ll let others handle the remaining packages where this would help.

Closing the bug!
