+Pip installed wheels are not reproducible currently. The direct_url
+files encode an installation path and the installed wheels compile
+the python files at their location, not their final install location
+which is incorrect.
+
+To fix this, simply disable the direct_urls and pass the "root" to
+the python compile function to strip that path out of the compiled
+files.
+
+A version of this patch, perhaps stripping root from the direct_urls
+may be something that could be considered by upstream.
