+Subject: [PATCH] modules/python.py: do not substitute python's install prefix
+ with meson's
+
+Not sure why this is being done, but it
+a) relies on Python's internal variable substitution which may break in the future
+b) shouldn't be necessary as Python's prefix ought to be correct in the first place
+
