Good idea. It is actually the fastest. I've also tested bash 4.0.0
from "pkgsrc" which is even slower than the bundled bash 3.2.17.

Shell                   First build time        Second build time
=================================================================
/bin/sh (bash)          19mins 25secs           19mins 34secs
/bin/zsh                16mins 44secs           16mins 30secs
/usr/pkg/bin/pdksh      13mins 56secs           13mins 55secs
/bin/ksh                13mins 16secs           13mins 05secs
/usr/pkg/bin/bash       19mins 48secs           19mins 45secs

Unless there are any objection I'll switch Mac OS X (Leopard to
start with) to "/bin/ksh" after a reasonable amount of testing.

        Kind regards

P.S.: These number also demonstrate that it would be very worthwhile
      to provide C replacements for the buildlink wrappers.
