*cp310-cp310-musllinux_1_2_x86_64.whl contains a GNU compiled object?

[Adoni5]

We are having issues installing rpds-py on alpine 3.22 inside a docker container. The python 3.10 version is managed by uv. The actual error seen when trying to import rpds is ModuleNotFoundError: No module named 'rpds.rpds'.

However the install works fine in the same container using a uv managed python 3.11 version. On closer inspection the wheel for python 3.10 seems to suggest the shared object for bindings is in fact compiled by gnu rather than musl.

Forgive me if there's a basic misunderstanding here. The confusing part of this for me is that the install works and executes fine into a python environment that is managed by pyenv!
