Due to the changes introduced by #444 / #447 the environment variable SSH_KEY is no longer passed to the sludbuilder environment, however this variable is required by the build.sh script in slugbuilder to be able to clone buildpacks from private git repos, so this variable needs to be whitelisted.
Note: For other people running into this issue, you can work around it by editing the deis-builder deployment and changing the version of the builder image back to v2.5.5 until a fix is available.
