Can't install package 'jq' on raspberry pi

[le-mongrass]

Hello,
I try to use this script on a Raspberry Pi, but it's unable to locate jq.
Does somebody know how to use this script on Raspberry Pi.
The jq package can be found in wheezy backports.
https://packages.debian.org/wheezy-backports/jq
But why not on the Raspberry Pi?

Works for me
