The configure tests for db4 in cfengine-2.x spuriously fail on rh9
Other autoconf code that does similar local tests may also fail.
On Shrike, db.h lives in /usr/include/db4 but there is no corresponding
'libdb4.so' symlink.

        for d in /opt /usr/local /usr; do
            for v in db-4 db4 db3 db; do
                if test -f "$d/include/$v/db.h" ; then
                    test "x$d" != "x/usr" && BERKELEY_DB_LDFLAGS="-L$d/lib"
                    BERKELEY_DB_CFLAGS="-I$d/include/$v"
                    BERKELEY_DB_LIB="-l$v"
                    AC_MSG_RESULT($d)
                    break
                fi
            done

There are already a number of symlinks done in %install, could another line
be added like:
