erm, presuming that you installed the "rpm" from the SuSE disc, then it should be there, and available already.
If not, the put the disc in, copy the rpm to you tmp file, if it is acutally called an rpm, then you should be able to click on it and it SHOULD install itself.
If, it's a "xxx.tar" or "xxx.tar.gz" then follow cnjohnson's suggestion.
If you can't find it, then open a console and try "locate" whatever or "whereis" whatever.
Then at least, you will know where "it" is.
