building seamonkey - python setup - imp module

[Nils Breunese]

Python's imp module was deprecated in Python 3.4 in favor of ‘importlib’, and removed in Python 3.12.

This is confirmed by the deprecation warning printed by Python 3.11, which does still have the imp module:

❯ /opt/local/bin/python3.11
Python 3.11.10 (main, Sep  7 2024, 05:47:53) [Clang 15.0.0 (clang-1500.1.0.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import imp
<stdin>:1: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses

But it is indeed no longer present in Python 3.12:

❯ /opt/local/bin/python3.12        Python 3.12.6 (main, Sep  7 2024, 05:15:33) [Clang 15.0.0 (clang-1500.1.0.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import imp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named ‘imp'

I guess you’ll either need to use an older Python version, or patch SeaMonkey to use the importlib module instead.
