krb4-1.2.1

All older versions of krb4 before 1.1 or /usr/athena directories, which
where not cleaned up have /usr/athena/lib/lides.(a|so) lying there, same
with header file. The administrator has to delete them manually, after
installing newer krb4 version with openssl "support".

KTH KRB4 supported openssl I think since 1.1 release. Even with newer
version you canget libdes compiled and installed, you just say to
configure --without-openssl ^H^H^H^H^H--disable-openssl.

That's what I've done this time to test, if this would be solution to get
rid of des originating from openssl. ;)

If you plan to rename des.h to des_old.h, fine for me, then only one
des.h will be present. As I'm not a programmer, I can't comment the rest.
