rar binary for SuSE x86_64?

Hello, I'm a new SuSE user. I switched to SuSE 10.0 x86_64 from Fedora x86, and I'm loving it. I've noticed that the RAR RPM specifically for the x86_64 is not available in the SuSE distribution and it doesn't seem to be available anywhere on the web (I already have the UNRAR RPM installed for x86_64). This isn't a big deal because I downloaded the binary tarball of RAR for Linux from the RAR site and it works. But I'd rather use an RPM as specifically compiled for my current architecture as possible. Is this possibly because the UNRAR source is available and the RAR source is not? (I'm not sure if the rar source is available) I suppose that would explain why they couldn't make an x86_64 RPM? I'd appreciate some information. ~Mark
