Great idea and thanks for creating this library!

OS: Ubuntu 18.04 LTS Python: 3.9.6

Upon running:

pip3 install ruuid==0.3.0 --force --no-cache

and trying to use the package:

from ruuid import uuid4
Traceback (most recent call last):

I'm hoping we can avoid the need to ensure a certain libc version dependency?
