Starting with 9.0.7293 there is a ImportError present which blocks the building of the module on NixOS.

Can be reproduced on Fedora 24 in a clean venv after an installation from PyPI.

@twizmwazin something seems to have gone wrong in the automatic release process - chain_builder.py is not included in the pypi release.

[twizmwazin]

It looks like packages aren't declared correctly in setup.py, meaning currently angrop only works if you use -e mode with source. I can take care of this tomorrow.

[twizmwazin]

Fix merged, will be in the next release. Thanks for reporting!
