In a second patch I incorporated a statement
PATH=/bin:/usr/bin/:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin
Would this be sufficient?
That wouldn't be sufficent on NixOS, nor would it work for other unix
machines; some unixen install things in /opt, others in /usr/sw/ and
others in even weirder places. netstat could reside in any of those,
what we can expect is that one can find netstat (or similar) in the
current value of PATH; if not then that is a bug in how we check for
required programs.
