David,

Yep, you need to have ncgen to run gribtonc.  If fact you need to install
NetCDF and udunits to build gribtonc. If you already have NetCDF and
udunits installed, then the $PATH variable needs to be able to find the
ncgen.  It's a good test to run gribtonc from the command line first,
catches many of the errors.  The NetCDF package is on our UPC home page,
the udunits package is with the NetCDF package.
