20010327: hanging vg processes with dcredbook

Glenn,

I guess I should have added after replacing the Makefile:

cd $NAWIPS/unidata/ldmbridge/dcredbook
make clean
make all
make install
make clean


After you have the dcredbook_vg installed, then all you need to do is edit
your script and change dcredbook to dcredbook_vg and remove the gpend
line.
