installation from pip fails with an error on python 3.12.x

[devdattaT]

I have Python 3.12.3 on an Ubuntu 24.04 system, and when I run pip install pysupercluster, it fails with an error `AttributeError: 'dict' object has no attribute 'NUMPY_SETUP'

The complete example is as follows:

dev@lpt-23-acer:/tmp$ mkdir demo && cd demo
dev@lpt-23-acer:/tmp/demo$ python3 -m venv env
dev@lpt-23-acer:/tmp/demo$ source env/bin/activate
(env) dev@lpt-23-acer:/tmp/demo$ pip install pysupercluster
