Raspbian should be fine, but you do have to have enough dependencies installed.
In this case you need to apt install libffi-dev and openssl-dev; it will be
slow to build the first time (for each version of python) but it will speed up
a lot after that due to build caching.
(Specifically this is because it is building Cryptography, which does not yet
ship a manylinux1 wheel.)
Let me know if that works,
