What does it mean "<package> not tagged as an update candidate"?

["Richard W.M. Jones" <rjones redhat com>]

I'm trying to create an update for a new package (mingw32-freeglut,
https://bugzilla.redhat.com/show_bug.cgi?id=528892) in F-12, but I get
the error below:

  $ make update
  [...]
  Creating a new update for  mingw32-freeglut-2.6.0-0.1.rc1.fc12 
  mingw32-freeglut-2.6.0-0.1.rc1.fc12 not tagged as an update candidate

What does it mean?

Rich.
