I don't know if I'm reading bsd.apache.mk right (included due to the
dependency of apache webserver), but mod_auth_kerb may require apache
1.3, not 2.x

does your 8.1 have apache1.3?  Maybe it has both nd 1.3 is running?

I would bet that a 1.3 module won't work in 2.x

does apache2.x have a kerberos module?  there have been a ton of
additions to apache2.x

Let us know.
