I have exactly (not quite since there is not Linux but other OSes around,
OSF/1, HP-UX, Ultrix) the same problem.

A solution is to compile 'the world' using DES encryption.
(internat.freebsd.org) and
link /usr/lib/libcrypt.so.* -> /usr/lib/libdescrypt.so.*

(BTW, though I did the above I'm not yet seeing any DES encrypted
passwds in my master.passwd file). Maybe I have to reboot or even
built a new kernel?
