FWIW, I always assumed that Kerberos functions _were_ available when you ran
krb5-config --libs gssapi (why?  Well, because they were).  I'm not saying
that my assumption is necessarily valid, but in looking at krb5-config I
see that it only says what Sam has noted ("GSSAPI application with
Kerberos 5 bindings"), and I find that spetacularly vague.  I guess if
I was starting cold I'd look at the list of libraries it output, see
that "-lkrb5" was included, and figure that it would be safe to assume
that you'd get krb5 symbols as well (I guess when it comes to Kerberos
programming, I'm more de facto than de jure).
