Well, as noted before, the tutorial there relies on a very old setup, so you 
shouldn't be following it exactly.  The better approach is to:

1. Make a copy of the oplsaa.ff force field into your working directory
2. Modify its contents as needed to introduce any new atom types and bonded 
3. Write the .n2t file within that directory and make use of that one rather 
than any included in the force fields in $GMXLIB
