Right.  Per an email I received, the MIT Kerberos team doesn't test on
Solaris versions prior to 9, and Solaris 2.6 didn't have an IP version
6 implementation, so ipv6 compatibility is configured into MIT's krb5
by default.  It looks like I have three options to deal with this
issue:

1) Hack the Kerberos code to tell it not to include ipv6
2) Upgrade Solaris
3) Use a different Kerberos implementation

I can't *really* blame MIT for not testing compatibility with a
decade-old Solaris release, but I do wish they'd included a configure
option for disabling ipv6.
