No.

I have corrected the problem.  Get and install:
<http://groups.csail.mit.edu/mac/ftpdir/scm/scm-5e7-1.exe>

I added some text to:
<http://people.csail.mit.edu/jaffer/FreeSnell/nk.html#Building%20Databases>

  FreeSnell comes with a database of refractive-index spectra for
  several hundred materials.  If you want to add spectra of your own,
  it is probably better to create a separate database for them using:

      nk -F <path.rwb> --add <file.nk> ... 

  This way, mishaps while importing spectra will not wedge FreeSnell's
  nk.rwb.

  Multiple databases can be accessed simultaneously by design files.
