Problem building bonobo-activation

[Ghee Teo <ghee teo sun com>]

Hi,
   I am trying to build bonobo-activation both from the HEAD or 
gnome-2-2 branch on a linux box. I kept getting whole bunch of 
undefined symbols like:

gcc -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes 
-Wnested-externs -Wpointer-arith -Wno-unused -g -O2 -Wsign-promo 
-Wno-sign-compare -o .libs/activation-client client.o 
-Wl,--export-dynamic -pthread  
../bonobo-activation/.libs/libbonobo-activation.so -lORBitCosNaming-2 
-lORBit-2 /usr/lib/liblinc.so -lgmodule-2.0 -ldl -lgobject-2.0 
-lgthread-2.0 -lglib-2.0 /usr/lib/libxml2.so
-lz -lm -lname-server-2 /usr/lib/libpopt.so -Wl,--rpath -Wl,/opt/lib
client.o(.text+0x27c): In function `main':
/hacking/gnome/bonobo-activation/server/client.c:140: undefined 
reference to `Bonobo_ActivationContext_query'
client.o(.text+0x34e):/hacking/gnome/bonobo-activation/server/client.c:180: 
undefined reference to `Bonobo_ActivationContext_activate'
../bonobo-activation/.libs/libbonobo-activation.so: undefined reference 
to `POA_Bonobo_ActivationCallback__init'
../bonobo-activation/.libs/libbonobo-activation.so: undefined reference 
to `Bonobo_ObjectDirectory_unregister'
../bonobo-activation/.libs/libbonobo-activation.so: undefined reference 
to `TC_CORBA_sequence_Bonobo_ActivationProperty_struct'
....

Any idea how to go about the problem?
Thanks,
