I appreciate the explanation - makes perfect sense to me.  I'll just be 
"wary" each time I rebuild an SRPM to specify the %dist macro somewhere 
either in the spec or command line or whatever.  I just got caught by 
surprise that the packages I had just built were "incompatible" with my 
system - ie. caused dependency hell.
