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?
Your best bet is to go here and install the macOS 64-bit universal2 installer (that’s my copy of the link, in case of trouble may be best to go to the original page and download from there, under the Files section, 4th link down). That’s the one I used; next time I’ll go for a more up-to-date Python.
