Sorry for the previous mail. Apparently my mail app hadn't downloaded all the conversation and I just repeated things that were already said.
I agree that this is probably a bug and should be reported. Regarding the installation procedure, the updated instructions are in the TRUNK section [1]<http://opencast.jira.com/wiki/display/MHTRUNK/Install+Capture+Agent>, since you are using a non-yet-released branch.
