Both machines do not have a proper hardware random number generator.
One of them has been seeded before and saved the entropy
in /var/db/entropy-file.

On the one that has not, you can manually do it by writing 32 random
bytes to /dev/random with dd(1), eg. after extracting them from some
machine with newer cpu (and hardware random number support) or from 
the properly seeded machine by reading 32bytes from /dev/urandom.

Or you attach your ualea random generator usb dongle for a short while ;-)
