cross building NetBSD 4.0 problems

[Dieter <netbsd%sopwith.solgatos.com@localhost>]

I'm trying to build NetBSD 4.0 from sources.
Compile host: FreeBSD 7.0 amd64

Target arch     Results

 amd64     "Successful make build"

  i386   nbmake: don't know how to make [...] usr/lib/crtbeginS.o. Stop

 alpha   usr.bin/gdb53/opcodes/libopcodes.a(dis-buf.o): In function 
`perror_memory':
          : undefined reference to `dgettext'

Are these known problems, or am I doing something wrong?
