I did see some recent github commits to try and bring it up to 1.9 
workability, but until I can actually get it to run...dunno.

Wow ruby2cext looks fascinating.  It can even inline calls to core 
classes, like
def go
 "".center 3
end

gets translated to ruby C
VALUE go_c(VALUE self) {
  return 
(*(string_center_which_we_already_looked_up_at_load_time))(NUM2INT(3));
}

i.e. it avoids unnecessary function calls (if you pass it -O 
builtin_methods).
Thanks!
