+Subject: [PATCH] Fix python(abi) generator (the one written in Python)
+
+There were three problems:
+
+ - sys.version was not imported
+ - sys.version[:3] is not reliable on Python 3.10+
+ - distutils is deprecated on Python 3.10+
+
+We were not hit by the missing import in Fedora because we only run the script
+on .dist-info/.egg-info/.egg and not on .py files, so this if-branch never runs.
+
+But when the script was fed with a .py path, it errored:
+
+    Traceback (most recent call last):
+      File "/usr/lib/rpm/pythondistdeps.py", line 344, in <module>
+        purelib = get_python_lib(standard_lib=0, plat_specific=0).split(version[:3])[0]
+    NameError: name 'version' is not defined
+
+The sys.version[:3] thing kinda works for Python 3.10+ because *in this
+particular case* splitting on '3.1' and taking the prefix yields the same
+results as splitting on '3.10', but I consider that mere coincidence.
+
+Finally, since the distutils import happened at module-level,
+we got the Deprecation warning in all Fedora's Python packages:
+
+    /usr/lib/rpm/pythondistdeps.py:16: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12
