error building gnome-guile

["Andrew V. Shuvalov" <andrew ecsl cs sunysb edu>]

Hi!
   File  gnome-guile-0.13/guile-gtk/main.c has a code:

void
sgtk_init_main ()
{
#ifndef SCM_MAGIC_SNARFER
#include "main.x"
#endif /* SCM_MAGIC_SNARFER */
}

I get error : main.c:85: main.x: No such file or
directory
Where it can be?

Andrew
