Hi, sorrry I can't be more helpful, but here is a Python script that works. It only needs to be converted to Perl. :-)

From: python mouse delta

I put the code below for other monks to quickly see, and possibly help translate to Perl. Be aware you must run this as root to get access to /dev/input/mouse.

Re: Linux device filehandle roadblock seems to be a starting point for Perl. 

import struct

file = open( "/dev/input/mice", "rb" );

def getMouseEvent():
  buf = file.read(3);
  button = ord( buf[0] );
  bLeft = button & 0x1;
  bMiddle = ( button & 0x4 ) > 0;
  bRight = ( button & 0x2 ) > 0;
  x,y = struct.unpack( "bb", buf[1:] );
  print ("L:%d, M: %d, R: %d, x: %d, y: %d\n" % (bLeft,bMiddle,bRight,
+ x, y) );
  # return stuffs

while( 1 ):
  getMouseEvent();
file.close();
