  I would not have expected this code I wrote so many years go would generate such interest in quora, and end up here... :-)
  If you could post the log file we may know more, but this just made me realize this:
  pst-node and pst-plot are not even used in the code, so they are not necessary.
  maybe by merely omitting them it will compile for you.
  In any case, it is worth checking to figure out why pst-node is giving you an error.
  I am a pstricks guy, having learned it many years ago, so lean on pstricks and have not done much with tikz.
  I will see if I can make it work in tikz, but it is getting late now, so only tomorrow.
