You could try to compile gecode and gecodeJ with the same compiler as 
you used for your openoffice add-on and make sure they are linked 
against /opt/openoffice.org2.0/program/libstdc++.so.6

My guess is that your gecode libraries use libstdc++.so.6 with a 
different C++ ABI version.

Maybe someone  on this list is more familiar to these libstdc++ version 
problems than me, or you could try to ask that question on a g++ users list.
