Thanks, but I wonder how come such a large change is needed for
something that sounds like a simple problem with PATH.  Some of the
changes seem just style or change commands to equivalent ones.

Can you explain what exactly was the problem and how you solved it?
We can then discuss what needs to be changed in the instructions as
written.

Thanks.
