> This is a not problem. Please apply this patch to /usr/src/usr.bin/su/Makefile

In previous releases, a su generates 1 line in syslog.
In 3.0.1 a su generates 124 lines of cruft in syslog.
With or without the patch.

With the patch I don't get the "Undefined symbol" messages,
but I still get 124 lines of cruft.

su: in pam_sm_authenticate(): krb5_init_context failed: Device not configured
su: in openpam_dispatch(): pam_ksu.so: pam_sm_authenticate(): error in service module
su: in openpam_get_option(): entering: 'debug'
su: in openpam_get_option(): returning NULL
su: in openpam_dispatch(): calling pam_sm_authenticate() in pam_group.so

and so on, and on, and on...
