Bug#1061604: cctbx: autopkgtest regression

[Graham Inggs]

Source: cctbx
Version: 2023.12+ds2+~3.17.0+ds1-3
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Hi Maintainer

The cctbx's autopkgtest are failing [1], preventing migration.  I've
copied what I hope is the relevant part of the log below.

I suspect there are missing (test) dependencies.  Previously, gcc was
pulled in as a dependency through python3-pythran, through
python3-scipy.  This is currently not the case.

Regards
Graham
