* Allow for compilation to optionally use the MIT Kerberos 5 port like
now, but default to the base system's Heimdal.
* Use existing API to tell Heimdal's libkrb5 where the keytab is, rather
than exporting an environment variable (which is what must be done for
MIT's, apparently) -- this unbreak's specification of the keytab
location in httpd.conf.
* Rewrite the description to be far more accurate: no mention was made
of this module doing real SPNEGO/GSSAPI/Kerberos (as opposed to
"Kerberos password gateway") authentication.
* Bump PORTREVISION.
