Poking around it seems that you can, at least in Fedora land.  For example:

        %define day %(date | cut -c 1-3 -)
        BuildRequires: %{day} >= 17

This fails the build saying that that "Thu >= 17 is needed by ...".

Inside the %() it seems to be possible to have a pipe chain and nested
commands using back-ticks.  Here's an example I found by googling around:

        http://kmymoney2.sourceforge.net/phb/rpm-example.html

The 'distver' macro looks about the level of complexity we'd need,
excluding the need to override it.
