The includes are there, in /usr/include/fox-1.4.
The rubygems log is attached.  It seems to me a bug in the FOX
includes.  The scope resolution of the friend functions is determined by
their previous appearance according to the C++ spec, not by its friend
definition, if I understand correctly.
The swig wrappers look for FX::plane() and FX::normal(), which are never
defined in my 1.4 includes (only their friend declaration appears).

The bug in the fox includes is similar to this:

namespace FX
  // int f( int, int, int );
  // int f( float, float );

  struct A
    friend int f( int, int, int );
    friend int f( float, float );


int func()
  return FX::f(1,2,3);

This will not compile unless the two define lines are commented out.
