mpxblk missing - Githubissues

I must be missing something as the tool mpxblk is missing? Or is it something to get from SIMH?

Files I have in /system

root@remlazar:/home/jsteve/src/nbc/nbc-1.4# ls /system/bin

chgrp     clb    date   false  make   m.mpxmac  m.mpxmac3x  mv        nbccom  nbyacc  rlog      sh

I set the path like this: PATH=$PATH:/system/bin: clean/clobber doesn't... clean /system sooo rm -rf /system/*;make clean;make clobber;make install

to rebuild.
