[horde] Installing Horde on a shared server?

[S. Petty]

I'd like to install my own Horde framework on a shared server with
Site5.  I'm running into problems trying to figure out how to create the
databases, as I obviously don't have root access to mySQL.

All my mySQL databases get named like mysite_database name.   So, I'd
have to create mysite_horde.

Has anyone ever installed their own copy of Horde in a shared server
environment?  Am I going to have to create the databases by hand, or can
I modify the create.mysql.sql script?

Any suggestions would be appreciated.
