Hi Xeno, it looks like the code was ported to work with Ruby 1.9 and
didn't bother maintaining 1.8.5 (or 1.8.6?) compatibility.

What happens when you add the following to misc.c?

  #ifndef RSTRING_PTR
  #  define RSTRING_PTR(s) (RSTRING(s)->ptr)
  #endif
  #ifndef RSTRING_LEN
  #  define RSTRING_LEN(s) (RSTRING(s)->len)
  #endif
