My "vat" port depends on include files in the gsm port's build directory.
I could hardcode in "${PORTSDIR}/audio/gsm/work/gsm-1.0-pl10", but given
that 2.1.5 had gsm1.0.7 and -current has gsm1.0.10, I'm hesitant to do
that.  Does anyone see anything wrong with the following Makefile construct
(other than that it's hairy)?

GSM_DIR=        ${PORTSDIR}/audio/gsm
# Grunge the GSM work directory out of the port makefile.
CONFIGURE_ARGS= --with-gsm=`awk '/^WRKSRC=/ { sub(/$$[{(]?WRKDIR[})]?/, WRKDIR,
$$2); print $$2 }' WRKDIR=${GSM_DIR}/work ${GSM_DIR}/Makefile`

This should handle all of

WRKSRC=		$WRKDIR/foo
WRKSRC=		$(WRKDIR)/foo
WRKSRC=		${WRKDIR}/foo

Thanks,
  Bill

(I previously used `echo ${GSM_DIR}/work/gsm*`, but got worried about someone
not cleaning out their "work" directory after the gsm port got updated and
having both gsm-1.0-pl7 and gsm-1.0-pl10 directories present)
