Maybe related to #7125

Confirmed #7125 fixes things. Was getting a similar error but for libssl. Manually installing pkg-config via brew allowed my program to correctly resolve that lib.

Hey @jcamiel and @Blacksmoke16. We working on that issue already. Should be fixed in the next release. Before it you may avoid that error with manual install of dependencies or pkg-config package in runtime with any of available methods.

Was getting a similar error but for libssl.

The Runner Image Version is 20230214.2.
The working job executed few day before : https://github.com/python/cpython/actions/runs/4179085476/jobs/7238623120 (Runner Image Version is 20230205.1).
