oops I'm sorry, bind uses an epoch of 30 for FE5 these days, Enrico
said it used an epoch of 0 today (or that is how I intrepreted his
message).

So I am not really sure with how bind versioning numbers work and why
it's epoch is increased so much, but for a Fedora package you should
specify the epoch with bind to ensure the proper version.

If you want to make your spec file work with other distros you would
have to do something like:

%if 0%{?suse_version}
Requires:  bind >= 0:9.3 (or whatever epoch suse uses)
%else
Requires: bind >= 30:9.3
%endif
