This issue, the portmapper, threw me for a long time.  Is it still not 
built into busybox?  I have to build this separately (and ended up having 
to make a couple of tiny patches for out of tree building to work).  I 
downloaded portmap-6.0 from http://neil.brown.name/portmap/ .

Presumably it would be worth pulling portmap.c into busybox?  I've often 
wondered why it's not there, don't know how much work would be needed to 
do that.


The patches I needed are below, and I use this command to cross compile it 
out of tree:

PORTMAP_PROGRAMS = portmap pmap_dump pmap_set
build:
        make -C $(O) -f $(srcdir)/Makefile $(PORTMAP_PROGRAMS) \
            srcdir=$(srcdir) VPATH=$(srcdir) \
            CC=$(COMPILER_PREFIX)-gcc CFLAGS='$(CFLAGS)' NO_TCP_WRAPPER=y
