Unable to instantiate main class in linux

[Wemmy0]

I cloned the repo and created a library using python setup.py sdist
(I'm not sure if this is right, there are a lot of references to a Steamworks.py file that I can't find anywhere)

I then installed this with pip install dist/steamworks-2.0.0.tar.gz which suceeded.

Trying:

from steamworks import STEAMWORKS

steamworks = STEAMWORKS()
steamworks.initialize()

Throws the error:

Traceback (most recent call last):
  File "/home/******/PycharmProjects/SamRevitalised/main.py", line 5, in <module>
    steamworks = STEAMWORKS()
                 ^^^^^^^^^^^^

OSError: /home/******/PycharmProjects/SamRevitalised/SteamworksPy.so: undefined symbol: SteamAPI_Init

This may be due to I'm using this v1.6.1 SteamworksPy.so which seems very outdated but it's the most recent pre-compiled linux build. Trying to build from source results in this build error
