[imp] Dimp installation problem

[Werner Cyrmon]

Hi
I have a running horde/imp/kronlolith ... installation.
Yesterday I added dimp (following the steps in docs/INSTALLATION)
But when I click on dimp in the Settings menue I get:
Fatal error: Call to undefined method Horde::disableautoloadhordejs()  
in /usr/local/www/horde/dimp/lib/DIMP.php on line 63
Whats wrong here?
Thx for any help
Werner
