The POST script runs in the directory in which you ran condor_submit_dag, 
unless the relevant node has a DIR set in the DAG file -- in that case,
the POST script runs in the directory specified by the DIR value.

This doesn't seem like a problem with the directory -- DAGMan found the
POST script executable, but it wouldn't run.  What happens if you just
run "./extract_output 3ebr-00003.output.zip" directly on the command line?

Yes, the -outfile_dir argument just tells DAGMan where to put the 
dagman.out file.  (See the man page:
http://www.cs.wisc.edu/condor/manual/v7.5/condor_submit_dag.html).
