Bug#1086577: amp FTBFS with python >= 3.12: No module named 'numpy.distutils'

[Stefano Rivera]

Source: amp
Version: 0.6.1-1
Severity: serious
Tags: ftbfs
Justification: FTBFS

Dear maintainer,

During a test rebuild, amp failed to rebuild.

Probably related to #1067375, numpy.distutils is deprecated and was
removed when building with Python >= 3.12:
https://numpy.org/doc/2.1/reference/distutils.html#module-numpy.distutils

During handling of the above exception, another exception occurred:

    raise RuntimeError(msg)
RuntimeError: Please install numpy (version 1.7.0 or greater) before installing Amp. (Amp uses numpy's installer so it can compile the fortran modules with f2py.) You should be able to do this with a command like:   $ pip install numpy

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here (for the next 30 days):
https://debusine.debian.net/artifact/929918/

About the archive rebuild: The build was made on debusine.debian.net,
on arm64 using sbuild.

You can find the build task here:
https://debusine.debian.net/work-request/42373/

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks,

Stefano
