Hi Leonardo,
Have you tried installing Mandrake in Portuguese, this could possibly be an easier way
of sorting out your problem. For the StarOffice part , look under the non-kde
applications item of your K-Menu you should be able to find an icon for StarOffice. If
you do not have one then after you've installed StarOffice you should have restarted
kde and this is done in one of the items of your K-Menu ( the little K that you see in
the far- bottom left of your screen). Also StarOffice does not need to be installed as
root . If you've created yourself a user account you should be able to install
StarOffice easily with no need of root's intervention. Please feel free to email me
personally if you need any help in Portuguese.
Hope this helps.
Tchau
