[ale] rpm that isn't

[rebus at mindspring.com (jim)]

Since I had no luck at all with the Real Player I got from real.com, I
decided to try the latest updated rpm for it from the Red Hat ftp site.
It had the .rpm suffix, followed by .rhmask-5 (I assume for Red Hat
5.0). But rpm tells me this is not an rpm file and won't install it. If
I remove .rhmask-5, the response is the same. It IS supposed to load,
isn't it?
