On a system where DES encrypted passwords are in use:

# ls -l /usr/lib/libcrypt[_.]*
lrwxr-xr-x  1 root  wheel  13 May  2 13:11 /usr/lib/libcrypt.a ->
libdescrypt.a
lrwxr-xr-x  1 root  wheel  14 May  2 13:11 /usr/lib/libcrypt.so ->
libdescrypt.so
lrwxr-xr-x  1 root  wheel  16 May  2 13:11 /usr/lib/libcrypt.so.2 ->
libdescrypt.so.2
lrwxr-xr-x  1 root  wheel  15 May  2 13:11 /usr/lib/libcrypt_p.a ->
libdescrypt_p.a
#

To switch the MD5 scheme, these four symlinks should be replaced with
symlinks to these four corresponding MD5 libraries:

# ls -l /usr/lib/libscrypt[_.]*
-r--r--r--  1 root  wheel  9190 May  2 13:11 /usr/lib/libscrypt.a
lrwxr-xr-x  1 root  wheel    14 May  2 13:11 /usr/lib/libscrypt.so ->
libscrypt.so.2
-r--r--r--  1 root  wheel  6460 May  2 13:11 /usr/lib/libscrypt.so.2
-r--r--r--  1 root  wheel  9940 May  2 13:11 /usr/lib/libscrypt_p.a
