[newbie] Problems with RPM

[Terry S.]

I want to install some programs on my computer, but when I try to use 
Mandrake's Software Manager, it keeps telling me that the packages I'm trying 
to install are already installed.  I can verify that none of the packages are 
installed by using:

rpm -q --all

and even install them using the command line, but Software Manager just 
doesn't want to do it.

Any suggestions?
