 That doesn't work, you can't specify arch like that and you can't
specify the version in that way.
 In later versions of rpm (Eg. RHEL-6) you can use %{_isa} ... and in
theory you can hardcode both isa's, but I'm not sure how supported that
usecase is.
 In RHEL-5 you can do one of two things:

1. Provide something unique in both arches, and require both provides.
Icky, but should work (some packages in RHEL-5 do this, IIRC).

2. Pick a file from each package that is only provided by it, and
require those (I've heard of packages doing this, but I'm not sure there
are any in RHEL-5).

...in general though I'd recommend people not try to put "policy" in the
rpms, and do it some other way.
