[ingo] Ingo error -Unable to load the transport driver "Ingo_Transport_".

[Paul Griffith]

Hi Everyone,

    I am in the process of upgrading a very old installation of Horde to 
the latest version. I am running into a issue with Ingo. Currently we 
are running Ingo 1.2.1 and am trying to migrate the database to the new 
installation (Ingo 3.2.4).  When I try to convert the current filters 
from the preferences backend to the new database table, I get the 
following error.

ingo-convert-prefs-to-sql
php ingo-convert-prefs-to-sql < filename
Fatal Error:
Unable to load the transport driver "Ingo_Transport_".

What do I need to fix this error.

Thank You
Paul
