I see no problem using my installation -- see below. I suggest that
you check that you really have installed all the files required,
including _gclsort by Philippe Van Kerm (available on SSC). (The
latter requirement is specified in the help file, the SJ article, and
the pre-print of the article available as an ISER Working Paper.)
