Bug#615605: libjson-perl: upgrade libjson-pp-perl from Recommends to Depends

[Jonathan Yu]

Package: libjson-perl
Version: 2.27-1
Severity: important


Due to a misunderstanding as to the intent of this package, and its
relation to JSON::PP (see libjson-pp-perl), JSON::PP was considered a
Recommends rather than a Depends.

In a discussion with David Golden, it was identified that this package
should be considered a Depends. The JSON::backportPP module was not meant
to be used in normal circumstances:

  Will work, but was not designed to be used that way.  The
  JSON::backportPP was a stopgap to ensure that if something went wrong
  with the split of JSON::PP, that JSON would still have a pure-perl
  fallback.  It's an engineering safety, not an intended user API.
