Cassandra python driver - undefined symbol

I am trying to run the python Cassandra driver on AWS lambda. I followed the amazon guide on how to build the deployment package with the cassandra-driver dependency. I still cannot get it work because of this error:

Unable to import module 'login': /var/task/cassandra/cluster.so: undefined symbol: PyFPE_jbuf

I found another S.O. question related to this issue, in which is stated that driver version 3.7.1 solves the problem (and that can be confirmed here), however I am still getting it.

Is anyone having the same issue running the python driver on aws lambda?

Thank you

In case someone is experiencing the same issue, after many attempts, I solved it building the package using an EC2 instance running the Amazon Linux AMI.

I don't know actually the exact reason, but pip via virtualenv was not generating the lib64 folder on my laptop (Ubuntu 16.04), which I got instead on the EC2 instances and that has been populated with additional files while installing the cassandra-driver package and related dependencies (futures, six).
