If you don't select DES libraries at install-time (or install them some other way), then you get MD5 passwords, which are arguably "better" in many ways. If you do install DES libraries, you automatically get DES passwords. You can change this with a bit of hackery in libcrypt - I have a mostly-completed replacement to libcrypt which fixes this but it may be some time before I can get it committed. Moral: don't install the DES libraries unless you need them. "Installed" means which copy is pointed to by the libcrypt.* symlinks in /usr/lib - to switch between DES and MD5 if you have them both then you just re-point the symlinks. If you have DES libraries installed, your system can understand both existing DES and MD5 passwords, but if you have MD5 then you can't use existing DES passwords.
