gnucash won't start up

[Roger]

I have Kubuntu 12.10 (not intentional) and gnucash 2.4.10 through the 
repository which used to work with Kubuntu 11.04.

Now it quits on startup with the following message:

gnucash: error while loading shared libraries: libgnc-gnome.so.0: cannot 
open shared object file: No such file or directory

When I tried it on another laptop with Kubuntu 12.04 and gnucash 2.4.10 
from the repository which also used to work with Kubuntu 11.04

It didn't start either displaying a similar message:

gnucash: error while loading shared libraries: libguile.so.12: cannot 
open shared object file: No such file or directory

Googling doesn't provide any clues so I would appreciate some help in 
resolving these issues.
