SMLNJ installation problem

I've got a problem with my SMLNJ installation.

Whenever I start an sml process (through Emacs or from the command
line), I run the following program to make sure that values are
printed 'properly':

structure AdjustPrinter
= struct
    val _ = Compiler.Control.Print.printDepth := 100
    val _ = Compiler.Control.Print.printLength := 100
  end

When running SMLNJ v110.62 or v110.67 under Kubuntu, I get the
following error message:

/home/cnn/.emacs.d/print.sml:5.13-5.46 Error: unbound structure:
Control in path Compiler.Control.Print.printDepth
/home/cnn/.emacs.d/print.sml:6.13-6.47 Error: unbound structure:
Control in path Compiler.Control.Print.printLength

At my school, where I'm running SMLNJ v110.0.6, it works fine. Anyone
know why?
