modules.dep problems

[Gordon Dykes <Gordond@appleonline.net>]

I have just installed the 2.2.18pre21 kernel image and have problems 
loading the modules.
When i boot in to linux this message is shown
   depmod *** cant open dependencies files in /lib/modules/2.2.17/modules.dep

I have played with depmod, update-modules and modules config and got 
very similar responses.
I have uninstalled the 2.2.17 kernel image through dselect and want 
to use the 2.2.18 kernel.

How can i get the modules to work and configured.

Your time is much appreciated.
