Judging from your first quote block, you seems to be installing bgpstream version 1 using home brew. The pip version of pybgpstream (2.0) supports only libbgpstream v2 (see release note). You should try install v2 bgpstream then try again. Also, the homebrew version is not maintained by CAIDA (yet).

With that, I can't reproduce the issue on Mojave where I have libbgpstream v2 installed:

• No issues doing pip3 install --upgrade --force-reinstall pybgpstream and import pybgpstream on 10.14.5.
• No issues doing that on 10.14.6
• I don't have a machine that runs catalina on hand, so cannot verify that yet.

Try this most recent release of libbgpstream v2 rc3 here:
https://github.com/CAIDA/libbgpstream/releases/tag/v2.0-rc3

I managed to successfully brew install bgpstream and then pip install pybgpstream on macOS 12.5 just now by setting C_INCLUDE_PATH and LIBRARY_PATH:

Note that Homebrew does now happily install libbgpstream 2. Maintainers, you may want to update the "Coming Soon" on https://bgpstream.caida.org/docs/install/bgpstream#osx to say that it works!
