you need to add the packman repository to get access to a SUSE rpm for rtorrent.
go to yast
click software, then software repositories
click add ( down left)
choose specify url
url : Index of /suse/11.0
click next and finish
then go to yast>software again, choose software management.
here, search for rtorrent
you should find 3 results, the first being rtorrent, the other 2 debug info and debug source.
just install rtorrent.
after all this, don’t forget to get the example .rtorrent.rc script to config the client propperly.
hope this helps,
if you have any probs at all, feel free to pm me.
