EDIT: I reflashed using the Hentges version of the OZ 3.5.3 rom and now have the apps below working fine. I don't understand why there are such strange dependency problems with the default install of OZ, but I figure it is because of little known tricks and tips that have yet to be documented.
I tried to free up space on root by moving the Opie-PIM apps (big mistake, didn't gain anything on root), and now when I try to install Opie-addressbook I get the following.
root@collie:~# ipkg install --force-depends -d sd opie-addressbook

Nothing to be done
An error ocurred, return value: 1.
Collected errors:
Warning: Cannot satisfy the following dependencies for opie-addressbook:
libqpe1 (>= 1.2.0) libqte2 (>= 2.3.10)
root@collie:~#
Now, I know force depends will override the constant libqte/libqpe error, but it fails due to opie-pics?

Ideas? Must I reflash yet again?
