I have a build of gdb for an Ada toolchain, and it appears there is a reference to a Python dynamic library that does not exist on my system (Intel Mac, Ventura 13.4.1 (c)).

$ which gdb
/opt/gcc-13.1.0/bin/gdb

$ gdb

I have installed Python via brew. Where should I look for the required library (so I can set DYLD_LIBRARY_PATH), or how can I install the proper one?
