Comment (by kencu):

 Marius,

 that patch needed one more #endif to work, but did work
 {{{
 $ port -v installed gnutls
 The following ports are currently installed:
   gnutls @3.3.21_0 platform='darwin 8' archs='ppc'
 date='2016-03-01T11:45:13-0800'
   gnutls @3.4.13_0 platform='darwin 8' archs='ppc'
 date='2016-07-11T19:36:18-0700'
   gnutls @3.4.14_0 platform='darwin 8' archs='ppc'
 date='2016-08-23T00:01:51-0700'
   gnutls @3.4.15_0 platform='darwin 8' archs='ppc'
 date='2016-09-13T22:48:22-0700'
   gnutls @3.4.16_1 platform='darwin 8' archs='ppc'
 date='2016-10-15T15:49:43-0700'
   gnutls @3.4.17_0 platform='darwin 8' archs='ppc'

   gnutls @3.5.8_0 platform='darwin 8' archs='ppc'

   gnutls @3.5.9_0 platform='darwin 8' archs='ppc'

   gnutls @3.5.10_0 platform='darwin 8' archs='ppc'
 date='2017-03-27T04:51:37-0700'
   gnutls @3.5.11_0 (active) platform='darwin 8' archs='ppc'
 date='2017-04-14T10:27:24-0700'
 }}}

 here's the revised bit
 {{{
 #ifdef __APPLE__
 # include <CoreFoundation/CoreFoundation.h>
 # include <Security/Security.h>
 #ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
 #if __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ >= 1050
 # include <Availability.h>
 #else
 # include <AvailabilityMacros.h>
 #endif
 #endif
 #endif
 }}}

 Of note, it also works perfectly well to do this instead:
 {{{
 sudo ln -s /usr/include/AvailabilityMacros.h /usr/include/Availability.h
 }}}
 even tho that is terribly evil and to be scorned. :>
