Hmm, I don't know what symbol it's using there.  I don't think libobjc2 uses 
any symbols not in the GNU namespace.  If it's not too much effort, could you 
recompile libobjc2 against libsupc++ (in ccmake, you'll see an option to 
explicitly select the C++ runtime to use)?  If it works, then I can do the 
release with a more explicit check for a compatible libsupc++.  If it doesn't, 
then I'll have to do a bit more testing...
