I would suggest that you try GCC 10 instead because (1) 11 was just
released and I would not be surprised if there are still issues with
the Homebrew port and (2) ODB 2.5.0-b.19 does not support GCC 11.

If, however, you would like to stick with GCC 11, then you can try
build2/ODB from the staging repository (the version of ODB there
supports GCC 11):
