You mean you want to specify the dependency's version in a macro, that you  
put into Requires:? If so, just use the macro in your build script, it'll be  
expanded, and you can test its value. Bare-bones shell isn't usually  
convenient for understanding most kinds of version number formats. You may  
need to do something fancy.
