Comment 1 for bug 922731

Pytz is normally shipped with Olson tzdata, but in this case the bundled version has been modified to instead read from the system tzdata.it

Graphite actually first tries to import pytz from the Python path, so if you were to install pytz using pip (or some other means) it would resolve this. In any case, I have added a check to search /usr/share/lib/zoneinfo as well as /usr/share/zoneinfo so that the bundled version works for Solaris as well.
