[Message part 1 (text/plain, inline)]

Hi Folks,

Here's my first attempt at a Guix package - a tool called Fabric which
is used for for web app deployment.

Couple of notes:

1. I found that I needed to upgrade python-paramiko to minimum 1.17.4 to
avoid an incompatibility between python-paramiko and newer
python-pycrypto. I'm not sure what the implications are of this.
Technically only the Python 2 version needs to be upgraded, since Fabric
is Python 2 only, but I've upgraded both for consistency.

2. I've disabled tests for now as they fail when the package attempts to
download the "test-require" dependency "fudge". What's the normal way to
stop the Python package doing it's own dependency downloading? Happy to
also package "python2-fudge", but that didn't fix the downloading issue.

Cheers,
Ben

Sounds good.

I would expect that adding python2-fudge would indeed fix the problem
(the setuptools machinery checks for already-available packages and only
tries to download as a last resort.)  Would need more investigation I
guess!

I’ve split it into two commits and applied.

Thank you, and welcome!
