debian-powerpc: can't install gnome-core/testing

[Brendan J Simon <brendan.simon@bigpond.com>]

I'm trying to do an 'apt-get upgrade' on my PowerBook running 
Debian/Testing.  It complained when trying to upgrade some gnome 
packages.  This has been going on for a while now.  It seems that 
gnome-core depends on libcapplet0 is the culprit.  gnome-core requires 
version 1:1.4.0.1-3 but the latest seems to be version 1:1.4.0.1-2.  The 
apt-get error message is :

Sorry, but the following packages have unmet dependencies:
 gnome-core: Depends: libcapplet0 (>= 1:1.4.0.1-3) but 1:1.4.0.1-2 is 
to be installed
E: Sorry, broken packages

Can I force this to install somehow or do I have to wait for libcapplet0 
to be upgraded to the required version ?

Thanks,
Brendan Simon.

PS: snmp has dependency problems too.  I'm not sure how the snmp and 
snmpd binaries are available to install yet the snmplib is not ???
