Sorry wrong traces, thought I installed right version. Corrected:

/usr/local/lib/python2.7/dist-packages/secp256k1-0.13.2-py2.7-linux-x86_64.egg/secp256k1/__init__.py:228: UserWarning: implicit cast from 'char *' to a different pointer type: will be forbidden in the future (check that the types are as you expect; use an explicit ffi.cast() if they are correct)

Just confirming I get the same error.
