Fix for Red Hat 9.0 Berkeley DB Error

[Rasheda M Menzies]

In order for configure to run, and not report a BerkeleyDB
error, on Red Hat 
9.0. The following line in the Berkeley DB section
(Line 7608 of cfengine-2.1.0b5):

                
if test -f "$d/include/$v/db.h" ; then

should be changed to:

                
if test -f "$d/include/$v/db.h" -a -f "$d/lib/lib$v.so"
; then



Regards,
Rasheda
