when condor_version is not in your path. Pegasus severly complains several times.
I don't think the condor not find should be an error. Even if it is an error the order does not seem to be correct.
First the condor_version was not found as a consequence the version was not determined.

Also why do you nede to run it 3 times. Shouldn't you cache the result in your bag of goodies that you pass around or just set a java property at that time and grab it again when you need it.
