skipping compilation in rpmbuild

[Dennis J.]

So I've just tried to rpm-build the current 5.2 alpha of mysql-workbench 
and while the compilation went through I got this error during the 
installation phase:

/usr/bin/install: will not overwrite just-created 
`/home/dennis/rpmbuild/BUILDROOT/mysql-workbench-5.2.1-1.fc11.x86_64/usr/share/mysql-workbench/data/default_toolbar.xml' 
with `default_toolbar.xml'

I got that fixed but calling rpmbuild with "--short-circuit -bi" only 
re-runs the install phase but doesn't create the packages.

Given that the compilation takes nearly an hour how can I tell rpmbuild to 
just go ahead and build the packages from the already compiled source?
