Firstly, thanks to Hussam and John for being there.

Actually, this was kinda my bad.  I installed hugemem yesterday, but restarted 
my server this morning.  Bothe the kernel and hugemem versions were 
2.4.21-52.EL.  Then, I tried to recompile dazuko, with the results I 
mentioned above.  However, I notice via up2date that new kernel versions were 
available, so in installed those, including kernel-2.4.21-52.EL and 
kernel-hugemem-2.4.21-52.EL.  When I compared /lib/modules/2.4.21-50.EL 
and /lib/modules/2.4.21-52.EL, I noticed that a lot was missing from the 
former.  So, I compiled dazuko thusly:

./comfigure --kernelsrcdir=/usr/src/linux-2.4.21-52.EL && more

and ... joy!  Of course, dazuko won't work until I reboot using 2.4.21-52, but 
that's certainly OK.  I have no idea what happened to the guts 
of /lib/modules/2.4.21-50.EL, cauing the dazuko compile to fail, but I'm good 
now (I think).

Hope you all understood my explanation.

Thanks again.
