C/C++ programs have to be linked against libraries that they use in addition to including the headers (it is kind of a dumb system). Without being linked against imp_atom, when you try to use the code, it can't find the imp_atom C++ library and so will fail to find a needed class.
In order to link imp_em against imp_atom, you need to add imp_atom to the list containing imp_core and imp_algebra in modules/em/SConscript.
