You need perl 5.7.1 or later, configured to use perlio (and not to use sfio)
Yes, this module is currently only suitable for the development branch of
perl

Note
  1: The features required for layers have only recently been added to
     development perl, so if your doesn't have the header perliol.h it's
     too old
  2: The perlio layers API has changed (at least once) between the initial
     version and 5.7.1, and may well change again. If so, it is quite
     possible that this module will fail to compile.
