Something goes wrong with SED now,
I don't understand what's happen , 

TOOLS_PLATFORM.sed?=            /usr/pkg/bin/nbsed
is defined in /pkg/obj/mk.conf.example, I look for SED with bmake -dvx and found
SED = ${TOOLS_PLATFORM.sed}

but in mk/platform/SunOS.mk, SED seems not defined at line
.if !exists(${SED}) || ${SED} == "/usr/xpg4/bin/sed"


here is the error:
--------------------------------------------------------------------------------
.././install-sh -c -m 444 linkfarm.cat1 /usr/pkg/man/cat1/linkfarm.0

===========================================================================

ERROR: pkgsrc now requires a more functional sed(1) than Solaris provides.
you can satisfy this requirement by running:

    cd /usr/pkgsrc/textproc/nbsed; /usr/pkg/bin/bmake install

this will install /usr/pkg/bin/nbsed and eliminate this message.
(nbsed is already installed by recent bootstrap-pkgsrc).
