Not sure I got the point across that the %prep section in the spec can
contain arbitrary commands, not just %setup and %patch.  Those arbitrary
commands might be executing things that are provided by the BuildRequires.

You can then say, well, it should look at %prep and decide whether to
pull the BuildRequires in or not, but that sounds like a bad idea in
terms of complexity for a crummy "feature".  You're presumably planning
to rebuild the thing at some point anyway.

BTW there is yum localinstall that takes care of requires, maybe it or a
relative can also do the same on SRPM BuildRequires?  Never tried it.
