Missing Redis dependency

[eric.lebigot@…]

Bokeh is missing a dependency on the "redis" port. In fact, running bokeh-server-2.7 (provided by py27-bokeh) yields the error in the PS. Installing the redis port fixes this.

If this is an optional dependency, it would be nice to get either a nicer error message, or at the very least some instructions about the fact that redis should be installed if the Bokeh server is needed (or did I miss this in the install messages?).

PS: Here is the error message:
