May be an issue with libexiv2python on macOS.
Machine Specifications:
- macOS Mojave
- Version 10.14.5
I get a similar issue trying to install on MacOS (Big Sur 11.2.3), it fails trying to install exiv2python:
% python3 -m pip install c2pa

I'm on Apple silicon (M1 chip).
I'm working my way through various setuptools and homebrew issues to get it working locally (brew install boost-python3 helped somewhat) but I'm having lots of issues with various libraries while trying to install py3exiv2 from source. I'll add to this issue if I can work it out, I just wanted to note that I'm working on it in case other people have issues.
Oops don't know how I missed this issue. I am having the same problem but filed in a new issue: #27
