I note that there have been a similar issue arising in https://github.com/2i2c-org/pilot-hubs/issues/144. I think their resolution was to install the package via conda that shipped with a pre-compiled version so that the compilation didn't need to happen at all rather than enabling the ability to compile as a user.
I'm linking a discussion in slack, related to #65 as well.
