Daniel,

Change applied in cvs, but only to the list_module_dep.sh script.  A similar
approach might be appropriate in other locations too, but I don't understand
how things fit together well enough to be confident.  In particular if we
direct some messages through stdout and some through stderr the order can
get mixed up, so it is likely best to only use stderr where we expect a
script or bash function is going to be called by other scripts that
capture stdout for use.

Best regards,
