Graphite install error 0.10.0-alpha

I get the following error when starting Graphite-web using DJango. 0.9.15 works ok, but I am looking to use the new "mapSeries" function available in 0.10.x

Seems to be a missing import -

Exception occurred processing WSGI script '/opt/graphite/conf/graphite.wsgi'.
Traceback (most recent call last):
File "/opt/graphite/conf/graphite.wsgi", line 46, in <module>
import graphite.metrics.search  # noqa
File "/opt/graphite/webapp/graphite/metrics/search.py", line 6, in <module>
from graphite.storage import is_pattern, match_entries
ImportError: cannot import name match_entries

I'm not a python programer, but maybe the package is missing in the setup.py?
