There's nothing wrong with that, except maybe an output buffering timing
issue, and running under cgiwrapd should eliminate that as a problem. 

If he's not getting output w/ cgiwrapd, there is something wrong with
the machine, that is not a cgiwrap issue.

I don't see any output from the script in those commands - he should be
getting at least the content-type header output, although it may still
be buffered.
