problem using rpm -ba with redhat fedora

[Francois Belliard ELIOS <francois belliard elios-informatique fr>]

Hello,

I have a RedHat Fedora version installed  and i am trying to build a 
package with the "rpm" command" but I get the following error :
   # rpm -ba test.spec
   -ba: option iconnue
           (means "unknown option" in english)

It looks like rpm does not know how to make a package.
Does anyone know something about this error ?

The following packages are installed on the station :
# rpm -q -a | grep -i rpm
rpm-python-4.3.1-0.3
rpm-4.3.1-0.3
rpm-devel-4.3.1-0.3
redhat-java-rpm-scripts-1.0.3-2
rpm-build-4.3.1-0.3
redhat-rpm-config-8.0.28-1.1.1
