+In my efforts to fix all Calibre tests, this test would always complain about
+backports.functools_lru_cache not existing even after I packaged and added
+python2-soupsieve as an input and confirmed it was in the
+PYTHONPATH. Currently Calibre does not actually use it for anything other than
+testing it's there, so I assume they will start using it in future Calibre
+versions.
