Either move the created library to (/usr)/lib, or add the current 
directory to the LD_LIBRARY_PATH environment variable. However, note 
that shared library creation isn't really working yet (the init 
routines of the necessary units, such as the system unit, aren't called 
so routines that rely on that - such as most IO routines and the heap 
manager - will not work)
