hey i have a bit of a problem installing gnumeric, and i was wondering if anyone cud help??

i added the repository http://www.maemo.org.br/platform/apt - mistral/ to the application manager catalogue, but my app manager has problems updating the available packages.

so i went to the website and downloaded the gnumeric_1.7.0-1indt1_armel.deb file

but when i try to install it with the app manager, it says that there are missing packages:-
libgnomecanvas2-0
lignnomeprint2-0
libgnomeprintui2-0
libgoffice0-3
libgsf1-114
libgsf-gnome1-114
gnumeric-common

so i downloaded these off the website too, but if i try to install one of them, it says 'incompatible package'

what can i do????

many thanks
