I can't see why this is happening off hand, but generally that means
that either the trailing "." is missing from the command that was
actually executed, or that argument getting "eaten" by some other
option. You might try printing out out ${COMMAND} immediately before
running it, just to make sure nothing obvious is missing that way.
(Also, any particular reason you are using "exec" here? I don't know
why it would be eating the "." under ksh, but you might try without that
and see if the problem goes away.)
Worst case, try adding the name of a file found in your
/export/herbarium directory after the "." and see if that at least
allows gtar to run.
