request build on just one arch ?

[David Timms]

Hi,

I receive a build result message:
  696 (audacity-freeworld): Build on target fedora-8-rpmfusion_free 
succeeded.
      Build logs may be found at 
http://buildsys.rpmfusion.org/logs/fedora-8-rpmfusion_free/696-audacity-freeworld-1.3.5-0.4.beta.fc8/

I notice a build did not complete {nor inform failure} for f8 on ppc64:
http://buildsys.rpmfusion.org/plague-results/fedora-8-rpmfusion_free/audacity-freeworld/1.3.5-0.4.beta.fc8/

I didn't receive a build failed message, so perhaps this job went awol, 
or the results/rpm did not copy back to the web server ?

If that is the case, is there a way to request a build for just one 
branch on one arch ?
