Sun's early access gnome-1.4 which installs into /opt/gnome-1.4
Guppi-0.35.5

configure fails to find dbopen
    Berkeley_db is installed with gnome 1.4 EA with
    libdb.so in /opt/gnome-1.4/lib
    db.h db_185.h in /opt/gnome-1.4/include
I'm able to add the required include/library flags but not being a configure
guru dont know how to do ths correctly.
The include needs to be propergated to doc-tools/Makefile
src/gnome/Makefile gets the required include set.

configure fails to find popt
    popt is installed with gnome 1.4 EA with
    libpopt.so in /install/gnome-1.4/lib
    popt.h in /opt/gnome-1.4/include
