Confirmed on Debian, installation succeeds and it's probably doing the right thing, but the warning should be addressed.

Here's the warning:

>> pkg install -forge communications
gf.cc:47:9: warning: 'OCTAVE__ERR_SQUARE_MATRIX_REQUIRED' macro redefined [-Wmacro-redefined]
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")
gf.cc:43:9: note: previous definition is here
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
1 warning generated.

Here's the code:

#include <octave/gripes.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
#include <octave/errwarn.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")

Maybe HAVE_OCTAVE_GRIPES_H and HAVE_OCTAVE_ERRWARN_H are not mutually exclusive, and that should be an "#else ifdef" or something there?
