[gradsusr] Problems opening Grib2 files with grads

[Wesley Ebisuzaki]

Javier,

The error message

> Open Error:  Data file type invalid
>   --> The invalid description file record is:
>   --> dtype grb2
says that you either are using gribmap v1 or gribmap v2 that was compiled
without grib2 support.  Most likely the former.
