port:unison +aqua fails to build

[RJVB (René Bertin)]

The aqua interface to the Unison file synchroniser fails to build (on OS X > 10.6):

• The Xcode project is set to build using the OS X 10.6 SDK, which isn't officially available on 10.9
• Providing it or after changing the project to build against the 10.9 SDK I get errors like the following:

  In file included from /Volumes/Debian/MP9/var/macports/build/_Volumes_Debian_MP9_var_macports_sources_rsync.macports.org_release_ports_net_unison/unison/work/unison-2.48.3/uimacnew/MyController.m:3:
  /Volumes/Debian/MP9/var/macports/build/_Volumes_Debian_MP9_var_macports_sources_rsync.macports.org_release_ports_net_unison/unison/work/unison-2.48.3/uimacnew/MyController.h:104:31: error: expected ')'
  - (BOOL)validateItem:(IBAction *) action;
                                ^
                                )
  

I'm clearly completely out of phase with current-day native OS X development and its tools, as I cannot seem to address that bug.
