NetBSD 2.0.2
port: i386

  

When I build my tools using 
 $ ./build.sh  tools  

 then I get this error.

Stop.
nbmake: stopped in /usr/src/tools/groff/obj/build

*** Failed target:  .build_done

*** Failed command:  (cd build && /usr/obj/TOOLDIR.i386/bin/nbmake bindir=

DESTDIR= INSTALL=/usr/obj/BUILDDIR.i386/bin/nbinstall\ -c\ \ -r src/include all)
*** Error code 1

I checked out the sources by doing:
setenv CVSROOT :pserver:anoncvs@anoncvs.NetBSD.org:/cvsroot

cvs checkout -rnetbsd-2-0 -P src

How do I specify the 2.0.1 branch ? 

     Thanks
