grads @2.2.1: Wrong default User Defined Plug-in Table

[ryandesign (Ryan Carsten Schmidt)]

I installed grads @2.2.1 and ran it and it said:

% grads

Grid Analysis and Display System (GrADS) Version 2.2.1

Config: v2.2.1 little-endian readline grib2 netcdf hdf4-sds hdf5 opendap-grids geotiff shapefile
Issue 'q config' and 'q gxconfig' commands for more detailed configuration information
Landscape mode? ('n' for portrait):  n
GX Package Initialization: Size = 8.5 11 
GX Package Error: Could not find a record for the printing plug-in named "Cairo" 
  * The environment variable GAUDPT has not been set
  * Unable to open the default User Defined Plug-in Table: /usr/local/lib/grads/udpt
  Please read the documentation at http://cola.gmu.edu/grads/gadoc/plugins.html
GX Package Terminated 

Why is the default User Defined Plug-in Table /usr/local/lib/grads/udpt? Shouldn't it be /opt/local/share/grads/udpt?

If I first export GAUDPT=/opt/local/share/grads/udpt first then it "works" in that it then gets to the problem reported in #64631.
