Hi Shanko,

 I think it's a Ruby bug that was fixed.

 Fri Jan 23 02:26:30 2004  Yukihiro Matsumoto

  * pack.c (num2i32): pack should not raise RangeError.
    [ruby-dev:22654]


 As a work-around, try changing line 73 in dl/types.rb
from:
 proc{|v| [v].pack("l").unpack("L")[0]}],
to:
 proc{|v| [v & 0xffffffff].pack("l").unpack("L")[0]}],
