rpm install problems

im trying to install some rpms so i can urn edonkey2000 for linux
i clicked on the 3 rpms i need and they would be checking stuff on my comp then the window would close
no error messege or this packege requires this or anything like that
so i try the command line way
"rpm -i ./gnet2-2.0.4-0.dag.rh90.i386.rpm"
and this is what i get
"warning: ./gnet2-2.0.4-0.dag.rh90.i386.rpm: V3 DSA signature: NOKEY, key ID 6b8d79e6
file /usr/lib/libgnet-2.0.so.0.0.4 from install of gnet2-2.0.4-0.dag.rh90 conflicts with file from package libgnet-2.0_0-2.0.4-1mdk"
then ir gives me command prompt again
when i installed libgnet-2.0_0-2.0.4-1mdk.i586.rpm it st there for a few seconds then gave me the cpmmand promt again so it installed
these files dont really concern me but this has happened befor
im just worried i dont have a bad packet manager

:edit:
i was on google searching for just the filename and version trying to see i there is a tar file or something but all i can find is rpm and atk or something like that
