Nightly composes of the robotics spin are not being done. You can look at
why the last one failed and that is probably the same issue release
engineering is seeing.

Error creating Live CD : Failed to build transaction : player-3.0.2-13.fc16.i686 requires libgeos-3.3.0.so

Apparently, it is fixed in player-3.0.2-14.fc16 which is in updates-testing repo. Can we do anything to use it for building the robotics spin?

Thanks again,
