I should have been more careful in what I wrote: all I meant was that
the inclusion of opt_inet6.h in src/sys/kgssapi/krb5/krb5_mech.c can
break the build of the kgssapi_krb5 module, and if this header is
really needed, then the module Makefile should probably be changed to
handle this header in the same way as is now done in other modules,
something along the lines of:

SRCS+=     opt_inet6.h
.if !defined(KERNBUILDDIR)
.if ${MK_INET6_SUPPORT} != "no"
opt_inet6.h:
     echo "#define INET6 1" > ${.TARGET}
.endif
.endif

This may not be the only problem with the module, as Rick Macklem suggested.

I meant, and should have written, "primary author of the NFSv4 code".
Obviously, from the commit message I cited, Doug Rabson and Isilon
were responsible for most of the kernel GSSAPI code.

Seconded:  a reference in the FreeBSD wiki would be helpful.
