Imagemagick version still shows as 6.5.7-8

If I push using git push heroku master I get

It seems like the buildpack isn't actually applying anything. My .buildpack looks like

https://github.com/mcollina/heroku-buildpack-graphicsmagick.git
https://github.com/heroku/heroku-buildpack-python.git

Completely no idea. This project unmaintained due to the impossibility of creating new builds of the project.

However, if you are on plain Cedar, and you have a fix for this I'll merge it straight away!

Hey thanks for getting back to me. I'm on the plain cedar stack not cedar-14.
