It depends on structure of your project. For example every rubygem-
package in Fedora requires rubygems-devel package, which ships the
macros file [1]. You can load such macro into your current spec file
using %load directive (but you have to have quite recent RPM, I believe
4.11+). Or of course, you can specify macros directly in your .spec file.
