In the archive, there is the file intern.h.diff. It corrects intern.h.

  $ cd /usr/lib/ruby/1.6/i586-linux-gnu
  $ mv intern.h intern.h.orig
  $ patch -p0 < intern.h.diff

If the above fails, correct intern.h with your hand. You only add
VALUE to rb_gc_mark() and rb_gc_mark_maybe() as follows:

  void rb_gc_mark()       -> void rb_gc_mark(VALUE)
  void rb_gc_mark_maybe() -> void rb_gc_mark_maybe(VALUE)
