Robert,

The relevant gempak routine is LC_FLOC. This routine searches in order:
sfstns.tbl
snstns.tbl
snworld.tbl

I think the third table should be sfworld rather than snworld
so I'm going to change it here as well.

After changing $GEMPAKHOME/src/gemlib/lc/lcfloc.f
recompile that routine with:
cd $GEMPAKHOME/src/gemlib/lc/
make clean
make all
make clean

Then rebuild gdthgt so that it links agains the updated gemlib:
cd $GEMPAKHOME/src/programs/gd/gdthgt
make clean
make all
make install
make clean

Alternatively, you can place a link from sfworld.tbl to snworld.tbl in
the directory you are running gdthgt from since it should look in the 
current working directory for the table first, then try in $GEMTBL/stns
if it is not a local table.
