I'm not an expert on "standard" *nix dynamic runtime stuff, but I think 
this maps to:

void * executable_handle = dlopen("path/to/executable");
void * symbol_address = dlsym(executable_handle, blah);
dlclose(executable_handle);

on most GNUstep-supported platforms. man dlopen may be a good starting 
point.

Ah, I didn't know about those limitations.
