How I solved "Failed cleaning build dir for cryptography"
(I came here from google to result for this error.)
note: using a virtualenv
my file /etc/apt/sources.list wasn't correctly configured for my debian 8.
I wanted to install paramiko. paramiko needs cryptography.
I got these errors:
first with pip install cryptography:
(...)

Failed cleaning build dir for cryptography
Failed to build cryptography

Command "/home/myuser/pyenvs/testo/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-HXWKAO/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-WjqY6V-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/myuser/pyenvs/testo/include/site/python2.7/cryptography" failed with error code 1 in /tmp/pip-build-HXWKAO/cryptography/
and then with sudo apt-get install build-essential :

(Not exactly the same errors as OP but I'm here to help eventually)
After testing almost every command from every posts I end up going on
https://wiki.debian.org/SourcesList
and copy pasted my adequate config in the file /etc/apt/sources.list
then:
sudo aptitude update
and then
sudo apt-get install build-essential libssl-dev libffi-dev python-dev
and then
pip install cryptography
