RPM query results?

[Kurt Granroth]

Here's an esoteric question for y'all.  What factors cause rpm to return 
different values for %{name} for the same spec file?

Okay, so I have the same spec file on all systems.  I then run the 
following query to get the current name:

rpm -q --queryformat "%{name}\n" --specfile project.spec

I run this on three CentOS 5 systems.  Two are x86_64 and one is i386. 
I don't know for sure that all three systems are running the same point 
version of CentOS5 (have almost no access to one of them).

The results I get are:

Remote x86_64 system:
project132-1.3.2-%{dist}
project132

Local i386 system:
project132
project132-debuginfo

Local x86_64 system:
project132

It's the *same* spec file on all three!  So what is causing them to give 
different results?  In particular, why does one give a -debuginfo 
version and the other a '-%{dist}' version?

I can provide the actual spec file in question, but not immediately. 
I'm hoping, at this point, that somebody will just *know* the answer.
