Toshio Kuratomi d6af6f8477 Update for modules which import json.
Some do not use the json module directly so don't need import json.
Some needed to fallback to simplejson with no traceback if neither was installed

Fixes #1298

module: pkgin
short_description: Package manager for SmartOS, NetBSD, et al.
description:
- "The standard package manager for SmartOS, but also usable on NetBSD
or any OS that uses C(pkgsrc). (Home: U(http://pkgin.net/))"
version_added: "1.0"
author:
- "Larry Gilbert (L2G)"
- "Shaun Zinck (@szinck)"
notes:
- "Known bug with pkgin < 0.8.0: if a package is removed and another
package depends on it, the other package will be silently removed as
well. New to Ansible 1.9: check-mode support."
options:
name:
description:
- Name of package to install/remove;
- multiple names may be given, separated by commas
required: true
state:
description:
- Intended state of the package
choices: [ 'present', 'absent' ]
required: false
default: present
'''
EXAMPLES = '''
# install package foo
- pkgin: name=foo state=present
# remove package foo
- pkgin: name=foo state=absent
# remove packages foo and bar
- pkgin: name=foo,bar state=absent
