Performing the following to resolve dependencies:
Install: gpm-devel.i386 0:1.20.1-66 - base
Install: ncurses-devel.i386 0:5.4-13 - base
It looks like your package came from the Fedora base repo. The message at the bottom means you have gpg checking turned on which is good, but you haven't imported the gpg keys yet.
To do that, try this command as root user:
rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora
Just in case you haven't done the livna key yet, that uses the command:
rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY
Also, if you are interested, here is the repo for Fedora extras with key instructions....
