If dev-libs/libverto was built with USE="-libev -libevent -tevent", mit-krb5kdc will fail to start with the following error in syslog: [krb5kdc] Cannot allocate memory - while creating main loop If at least one of those USE flags is enabled in libverto, mit-krb5 works fine. So dependency on dev-libs/libverto in app-crypt/mit-krb5-1.11.1 ebuild should be corrected accordingly.
