I upgraded to krb5-libs-1.2.1-16. This broke lpd in LPRng-3.6.26-1: #~ /etc/init.d/lpd start /usr/sbin/checkpc: error while loading shared libraries: /usr/sbin/checkpc: undefined symbol: stat /usr/sbin/lpd: error while loading shared libraries: /usr/sbin/lpd: undefined symbol: stat Reinstalling krb5-libs-1.2.1-8 fixed the problem.
Ooops, my bug report is a duplicate of bug #22195. Nonetheless, I think it's a kerberos lib problem, not lpd/checkpc. Therefore I let this bug open.
This was actually a bug in a previous version of krb5-libs, which should already be resolved in Raw Hide by relinking affected binaries.
