I thought so too, but the man pages suggest that may not be a requirement. Under Mac OS X, it looks like dlsym(RTLD_DEFAULT, "symbol") will look for the symbol anywhere. Under Linux it looks like dlopen(NULL, flags) will open a handle to the main program which can be passed to dyslm's first argument.
