Pear Dependency Problem?

I just installed roundcube-webmail on Ubuntu using synaptec. It's the newest version.
Edited the two config files, went to fire it up and get this message:

DB Error in /usr/share/roundcube-webmail/program/include/rcube_db.inc (63): DB Error: connect failed

Fatal error: Call to undefined method DB_Error::query() in /usr/share/roundcube-webmail/program/include/rcube_db.inc on line 124

Any ideas?

I walked away. Came back later and no more error. Not sure why.
However - I can only log in using one account. And that account isn't recieving or sending email, though no errors are displayed.

When I try to login with any user besides the one user that gets in, it just says "contacting localhost" and sits there.

I just checked the roundcubemail::users table and it contains only one username - that's the one I can login with. Any idea why it doesn't have the others?
