Pyo causes herokuapp to crash in Django Project

[kevindublin]

So I'm trying to put up a demo of a django project on Heroku that runs fine locally and loads when I uninstall the package Pyo, but it throws an OSerror when I reinstall it (OSError at / Exception Value: /app/.pyo/3.6_64/libs/libasound-fb332ab3.so.2.0.0: cannot open shared object -- see below for full traceback). I've added a buildpack that installs the libasound and recommened packages, but I still get the error. What am I missing? I see the Linux wheel fix symlink (https://github.com/belangeo/pyo/blob/master/pyo/_linux_wheel_fix_symlinks.py). Is the issue here? Are there C dependencies? Any help greatly appreciated.
