We had different issues here.
First, sort command used to sort variables and services names is
dependent on the local, so fix it to C to have consistent
results. C local is available on all systems.
Second, awk doesn't recognize \s escape char for space on OSX. This
resulted in indented check_required_vars calls being ignored. In fact,
all variables checked via indented check_required_vars calls (i.e. in
a fuction or conditional block) are actually *optional* variables, so
I changed the behavior to ignore those.
