GDBM problem during make

Hi all,

Running into a problem compiling 4.0.9 on a Solaris 10 6-06 box, patched to
the latest 10_Recommended patchlevel.  Also have lots of GNU software
already installed, for instance: autoconf 2.59, automake 1.9, bison 1.875,
flex 2.5, gcc 3.3.2, make 3.80, tcl 8.5, gdbm 1.83 (all from sunfreeware).

I compile using the following command:

./configure  --enable-bulldb=/var/spool/bulls --enable-auto-delete
--enable-server-mode --enable-standalone --enable-log-facility=LOG_LOCAL5
--enable-specialauth --with-pam --enable-shy
--enable-home-dir-mail=mail/.mail

Compile completes with no warnings at all.  However, here's the end of the
make output:

make: *** [popper_server] Error 2

What I have tried so far to no avail: 
-Reinstalling GDBM
-Adding the following to Makefile:
	DBM_LIBS        =       -L/usr/local/lib -lgdbm
	LIBS            =       ${NETWORK_LIBS} ${KERBEROS_LIBS} ${DBM_LIBS}

-Grepping the net for more help

Not sure what I'm missing here.  I have already been able to compile popper
without bulletin support, but I really need the bulletins.

I've seen this discussed all over the place, but can't find any resolutions
to any problems.

Anyone have any ideas???

Thanks!

Alex
