[gembud] GEMPAK 7 Troubles

I installed GEMPAK7-1.tar.gz and am running into some problems. RAP data is
fine, but NAM218 and GFS0.5deg files are giving me fits. A plot of 700
temps gives me DG-7 Input grid RELH ^140226/0000F000 @700 %PRES in SM5S
cannot be found.

The only thing I did after installing was copy over my previous
datatype.tbl file to match those up.

I still have 6.10 on the system and it is plotting the exact same files
just fine. Any thoughts?
