Minimum version of JSON::PP needs to be specified in Makefile.PL PREREQ_PM #2

I tried to install App::pmuninstall using cpanm on a custom compiled version of perl 5.10.1.

Install failed because it found JSON::PP, but the version (0.97) was older than the one it needed.

When I upgraded JSON::PP by hand and then tried again,, App::pmuninstall installed fine.

This line in Makefile.PL:

'JSON::PP' => 0,

Should be changed to indicate the minimum version required. I'm guessing it's something in 1.x or 2.x? It specifically failed when it could not find the decode_json export from the module.

Here's the verbose cpanm run where installation failed:

cpanm -v App::pmuninstall

It looks like decode_json first appeared in version 2.01 of JSON::PP. From the CHANGES file:

    [JSON::PP] (2.01 from 0.97)
        - updated JSON::PP for compatible to JSON::XS 2.01
        - renamed from_json and to_json to decode_json and encode_json

Pull request to resolve this in issue #3. Closing in favor of that issue.
