Issue with pip install fastjet

[alexbuzzi]

Using the following version of pip on my machine:

pip version: 24.1.2 machine: 2023 Macbook Pro - M3 Pro chip

running pip install fastjet gives the following error:

pip install fastjet

        File "/Users/user/mambaforge/lib/python3.10/subprocess.py", line 526, in run
          raise CalledProcessError(retcode, process.args,

      [end of output] 

  note: This error originates from a subprocess, and is likely not a problem with pip.

@alexbuzzi you're seeing this as there aren't yet Apple silicon compatible wheels for fastjet on PyPI (c.f. Issue https://github.com/scikit-hep/fastjet/issues/169). pip is then trying to build from the sdist but you don't have the necessary build tools locally installed.
