Trying to build security/gnutls (from HEAD updated 2007-06-05), I get:

gnutls_openpgp.c: In function 'gnutls_certificate_set_openpgp_keyring_mem':
gnutls_openpgp.c:944: error: too few arguments to function
'cdk_stream_tmp_from_mem'
gnumake[3]: *** [gnutls_openpgp.lo] Error 1
gnumake[2]: *** [all-recursive] Error 1
gnumake[1]: *** [all-recursive] Error 1
gnumake: *** [all] Error 2
*** Error code 2

Apparently the newly updated security/opencdk (0.6.0) is not compatible with
existing gnutls (1.6.3):

<http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00033.html>

Maybe the update for opencdk should be backed out for now, or if we need
opencdk-0.6.0, then gnutls should use

CONFIGURE_ARGS+= --with-included-opencdk

Cheers,
Mark
