Setting aside the "lessc" thing, I concur with that.  After installing
the relavant packages and having the metapackage register a bunch of
services, I have the following services and endpoints:

root at os-mgmt:~# keystone service-list

Yet the dashboard fails with an "Invalid service catalog service:
compute" exception (at
/usr/lib/python2.7/dist-packages/horizon/api/base.py in url_for, line
118).  However, as far as I could tell from the (very long and boring)
output of an strace invocation, no connection is even attempted to
keystone or to anything else, so maybe it's something that's only
related to horizon and not to keystone.  I freely admit my ignorance on
the matter, but maybe this will put someone on the right track to debug
that.

Roland.
