Python Cryptography external tests failing

[mattcaswell]

The Python Cryptography external tests are failing when run in Travis. It looks like they never really get started:

Ping @alex, @jon-oracle - Any ideas?

There seems to be some missing stdout/sderr, I don't see any of the expected output of python setup.py egg_info.

[mattcaswell]

@levitte - any idea where the missing stdout/stderr went?

[levitte]

I assume python setup.py egg_info gets executed as part of this line, right?:

pip install -q --requirement dev-requirements.txt

All I know is that before the building stage, there isn't much output when I run cryptography.py manually:

Can you remove the -q from the pip install line?

[levitte]

That can be done, of course.

#3007 is a PR where I'll experiment with what's needed. Note: I'm a python neophyte, so I will need help and suggestions.

[levitte]

So from a finally working #3007, is seems this is the issue
