Are you unaware IO#sysseek ? sysseek is actualy lseek.

------------------------------------------------------------- IO#sysseek
     ios.sysseek(offset, whence=SEEK_SET)   => integer
------------------------------------------------------------------------
     Seeks to a given _offset_ in the stream according to the value of
     _whence_ (see +IO#seek+ for values of _whence_). Returns the new
     offset into the file.

        f = File.new("testfile")
        f.sysseek(-13, IO::SEEK_END)   #=> 53
        f.sysread(10)                  #=> "And so on."

I guess open + sysseek +sysread will work for you.
