Hi Jo,
I recall it didn't work either, nor perldl (but I don't trust my
memory). I would have to start again to test them. As I wrote before,
my worry is the impression it might cause to new users to have a
program installed and then find out it sends error messages
(erroneous, as Ed explained above) when first tried.
Regards,
Luis
