Setup zoneminder on ubuntu 12.04 virtual server

vanilla server install (32bit)

1. Setting the resolution to 640×480 got me errors.

zmwatch[2429].ERR [Shared data size conflict in shared_data for monitor Monitor-1, expected 328, got 316]

Patching /usr/share/perl5/ZoneMinder/Memory.pm at line 130

The patch for i386 ($arch should be 32 here but perl uses 64 bit integer):
-----
  -our $arch = int(3.2*length(~0));
  +our $arch = 32; beyond 320x240
