You should be able to use the MIT Kerberos GSSAPI implementation fine
for this (but I think either MIT Kerberos or Heimdal would work; on
MacOS X it might be easier to use the native GSSAPI implementation which
would be Heimdal).  My understanding is that libcurl can link against
either Heimdal or MIT Kerberos, but you should probably investigate that
yourself.
