My understanding is that && and || have equal precedence, and this
seems to be borne out in testing at my shell. If the if/then method is
clearer I'm happy to go with that.

I think the problem is that there are earlier parts of the chain. It
currently looks like:

  foo &&
  bar &&
  do_something

but you are making it:

  foo &&
  bar || baz &&
  do_something

which will do_something whether or not "foo" is true. You need to put
your "||" at a lower precedence than the rest of the chain. The "if"
that Johannes mentioned works, though I think

  test_have_prereq PERL &&
  {
    test "$(uname -s)" != Darwin ||
    test "$(uname -r | cut -d. -f1)" -ge 13
  } &&
  ...

is more obvious to read (but that's subjective, of course).
