I've just updated pkgsrc tree and trying to bootstrap on Solaris

CC="cc" LIBC= MAKEFLAGS=
MAKESYSPATH=`pwd`/mk:mk:/opt/pkg/share/mk:/usr/share/mk:/usr/local/share/mk:/opt/share/mk ./bmake.boot
-f Makefile /opt/SUNWspro/bin/cc -xO3 -xtarget=ultra -Xa -xc99=all -xO3
-xtarget=ultra  -I../../libnbcompat -c /opt/pkg.obj/bmake/arch.c
"/opt/pkg.obj/bmake/make.h", line 99: cannot find include file: <sys/cdefs.h>
"/opt/pkg.obj/bmake/arch.c", line 562: undefined symbol: SARMAG
"/opt/pkg.obj/bmake/arch.c", line 566: incomplete struct/union/enum ar_hdr: arh
"/opt/pkg.obj/bmake/arch.c", line 591: undefined struct/union member: ar_name

... and so on.

Anyone knows a fix??
