I'm confused.  E.g., with the 2.0.4 RPMs we're testing:

$ sudo /usr/sbin/dtrace -vV
dtrace: D 2.0.3
This is DTrace 2.0.4
dtrace(1) version-control ID: 1ac1d4aaf8fb2ffa21187eb9e5227a487f7fcd40
libdtrace version-control ID: 1ac1d4aaf8fb2ffa21187eb9e5227a487f7fcd40

The "2.0.3" is _dtrace_version, which is DT_VERS_STRING, which is the 
highest version mkvers finds in versions.list.

The "2.0.4" is _DT_VERSION, which, um, okay, yeah, is set by 
GNUmakefile, which I guess gets it from "mkvers -vcurrent=t versions.list".

So if versions.list was missing 2.0.4, then how in the world could the 
RPM build report 2.0.4?  Where does that value come from?
