The xscreensaver package can detect krb5 and krb4 at ./configure time, but it assumes that krb5 has been built with krb4 support (and the code seems to require it). This is not the case for the USE='+kerberos -krb4' use-flags situation. I think the correct thing to do in this situation is either fail when this combination is detected, or disable the kerberos use-flag if krb4 isn't also enabled (with a warning, naturally).

thank you for your detailed report. i've chosen the second option for the moment, but i'm still not too happy with it. xscreensaver only seems to allow kerberos4 support only, or kerberos4 and kerberos5 support, but not kerberos5 only. this will have to do for now until someone has time to patch passwd-kerberos.c to make a kerberos5 only version.
Funny.

the fix is only in 4.10, it is currently the latest x86 stable xscreensaver. if you're using a diff arch open a new bug about it
