Fair enough. I know that several users of FreeBSD are complaining all
ready and have switched back to Bash-3.x.

This is a short script, named "t.sh" that will produce the error
message:

#!/usr/bin/env bash

if $(which gpg2); then
   printf "gpg2 located"
fi
   
This is the error message:

./t.sh: command substitution: line 4: syntax error near unexpected
token `)' ./t.sh: command substitution: line 4: `which gpg2)'

Even something as simple as:

echo $(uname)

will produce the same error message.

This is the output of bash --version
