Hi RP,

With some digging on upstream, more than perl version,
the building also requires to install perl Text::Template module
which does not exist in core perl, I think we have to add the recipe

[snip]
  Notes on Perl modules we use
  ----------------------------
  We make increasing use of Perl modules, and do our best to limit
  ourselves to core Perl modules to keep the requirements down. There
  are just a few exceptions:
  Test::More         We require the minimum version to be 0.96, which
                     appeared in Perl 5.13.4, because that version was
                     the first to have all the features we're using.
                     This module is required for testing only!  If you
                     don't plan on running the tests, you don't need to
                     bother with this one.

  Text::Template     This module is not part of the core Perl modules.
                     As a matter of fact, the core Perl modules do not
                     include any templating module to date.
                     This module is absolutely needed, configuration
depends on it.
