Are you sure about this?  They use different libstdc++ libraries but my 
understanding was the the C++ ABI was not broken between gcc-3.3/3.4/4.0.  In 
any event, incorrect library versions is the first problem he encountered (it 
is the one reported by the linker) and recompiling gtkmm would have solved 
both, if both exist.
