Thanks for you answer, however, I now get the following error:

#    objdir /usr/obj/sys/arch/spqrc/compile
===> Building kernel:    GENERIC.MP
===> Building directory: /usr/src/sys/arch/sparc/compile/obj/GENERIC.MP
rm -f a.out [Ee]rrs mklog core *.core .gdbinit
./build.sh: /usr/src/tooldir.NetBSD-2.1-sparc/bin/nbconfig: not found

ERROR: nbconfig failed for GENERIC.MP
*** BUILD ABORTED ***

Any ideas?  Thanks in advance!
