     Type:  defect         |     Status:  new
 Priority:  Normal         |  Milestone:
Component:  ports          |    Version:  2.3.1
 Keywords:                 |       Port:  octave-image
---------------------------+--------------------------------
 Build of octave-image under Mac OS 10.6 with Xcode 3.2.6 fails because the
 default compiler (`/usr/bin/c++` == `i686-apple-darwin10-g++-4.2.1`)
 doesn't support the `--std=cxx0` option.

 Error message:

 Attached is a very crude patch which selects `gcc-mp-4.8` under Mac OS
 10.6 (what about earlier?). It would probably be better to just specify
 that a c++ compiler with c++11 support is needed, but I don't know how to
 express it. If anybody can help... Thanks!
