GtkCellEditable_editing_done undeclared

Hallo, I am trying to compile php-gtk-2.0.1 under RH EL5 with php-5.1.6, gtk+-1.2.10, gcc-4.1.2 and autoconf-2.59. Configure doesn't believe that I have libglade2-2.6.0 installed, but that could be due to some strangeness of the RH setup. A REAL problem is that "make" dies with the errors of type... ext/gtk+/gen_gtk.c:1865: error: 'GtkCellEditable_editing_done' undeclared here (not in a function) ext/gtk+/gen_gtk.c:1865: error: initializer element is not constant ext/gtk+/gen_gtk.c:1865: error: (near initialization for 'gtkcelleditable_methods[0].handler') This is repeated for another 105 symbols continuing with GtkCellEditable_remove_widget and finishing with GtkTreeSortable_sort_column_changed. Since php-gtk-2.0.1 is now almost one year old and I do not think that I am a first person compiling it under RH EL5, my question is "does anybody know what's wrong here?"
