Generally it's better to fully qualify the paths to these programs in
the code. Is that difficult here?

I think all of these inputs are already available, so you can do e.g.:
(substitute "foo"
  (("'grep'") (which "grep))
  (("'gawk'") (which "gawk")))

...instead of referencing the inputs explicitly.
