homedir_cpan: Install libexpat1-dev needed for XML::Parser

.. otherwise you get the following error on Ubuntu 12.04

  Expat must be installed prior to building XML::Parser and I can't find
  it in the standard library directories. Install 'expat-devel' package with your
  OS package manager. See 'README'.

  Or you can download expat from:

  http://sourceforge.net/projects/expat/
