Comment 6 for bug 1402632

I just had the same issue on a completly fresh install of Ubuntu 14.04, so I ran this:

    pip install --upgrade --force-reinstall python-glanceclient

... and got this at the end:

    ...
    creating build/temp.linux-x86_64-2.7/src/cryptography/hazmat/bindings/__pycache__

    x86_64-linux-gnu-gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c src/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi_70441dc9x8be47966.c -o build/temp.linux-x86_64-2.7/src/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi_70441dc9x8be47966.o

     #include <openssl/aes.h>

                             ^

    compilation terminated.

    Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-YrIH3Q-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/cryptography

So I installed libssl-dev:

    apt-get install libssl-dev

And ran the above reinstall command again and it worked.
