During install of PyGObject, got:

../meson.build:31:9: ERROR: Dependency 'girepository-2.0' is required but not found.

Related to this issue?

• libgirepository-2.0 isn't available in standard raspberry sources...?
  So sudo apt install libgirepository-2.0-dev doesn't work...

As mentioned, quoting from the PyGObject changlog:

3.51.0 - 2025-02-01 (pre-release): From this version onwards girepository-2.0 is used for introspection. This means that you’ll need GLib >= 2.80.
(looks like this was released in vs 3.52.0 on 2025-03-09, any install after this would have failed).

Solution for now: use a version before 3.51.0. The previous version is 3.50.0 (from 2024-09-12).

To solve, I've altered the requirementsMTS250515.txt file to enforce this version, PyGObject==3.50.0.
