I am unable to use PyCuba, a Python interface for the multidimensional-integration library Cuba, on macOS 15.5. PyMultiNest, which requires PyCuba, is common for Bayesian analysis in the scientific literature, but nobody seems to have ever asked a question about it on StackOverflow.
% python3 -c 'import pycuba'
Traceback (most recent call last):

I tried "pip install cuba", which was sufficient on another user's macOS system. I tried "brew install cuba" as well. Also, attempting to compile a git-installation of Cuba failed:

Detected locale "C" with character encoding "US-ASCII", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
