That=E2=80=99s an issue in Guile=E2=80=99s compiler that Andy has been work= ing on recently. Static linking won=E2=80=99t help you. More generally, shared libraries (dynamic linking) are a way to save memory: those libraries are shared, meaning they can be loaded only once in memory even if there are many processes using them.
