pipefail doesn't work on NetBSD or FreeBSD

Can we do what we need with ()s?

For example:

( 
 ./waf configure --out=$DIR $2 2>&1
FOO=$?
) | tee    $DIR/test.log

That doesn't test the tee step, but the old bash code didn't do that either.

PS: The bash version didn't work on NetBSD or FreeBSD either.

-#!/usr/bin/env bash
-# sh on NetBSD and FreeBSD says:
-#   sh: ${PIPESTATUS[...}: Bad substitution
