[horde] hang on login

[Philip Goisman]

I installed Horde: 3.2-cvs, Imp: H3 (4.2-cvs), Ingo: H3 (1.2-cvs), and
Turba: H3 (2.2-cvs) on a redhat EL4 system.  Without Turba, login is
fast and smooth and all works as one would expect.  With Turba there
is a very long delay until connection.  With turba, the logs always
show the following:

Apr 23 22:02:49 HORDE [debug] [turba] Hook _horde_hook_share_init in application horde
not called. [on line 1448 of "/usr/share/pear/Horde.php"].

Since it's been over 10 months since someone last asked about this error; and,
since noone responded to the question, I figure the problem is mine.   
However, I'm clueless here.  I did see some recent messages on use_shares, but
apparently noone experiences the long hang until connection with Turba.

Any body have an idea on what it is I failed to do?
