I am using the boost serialization library version 1.3.4. This compiles fine. However, when I link it into my code, I am getting the following link errors: /home1/ken/main_gcc41/bld/sdpm/linobj/libsdpm.so: undefined reference to `boost::archive::basic_binary_oprimitive

::~basic_binary_oprimitive()'

/home1/ken/main_gcc41/bld/sdpm/linobj/libsdpm.so: undefined reference to `boost::archive::basic_binary_oprimitive

I am not seeing these using previous versions of the compiler.
