Installing Imagemagick for Heroku cedar-14 no such file or directory

[hardgolf]

hi, I have a difficulty in stalling this buildpack into my heroku app. The errors are

remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> Fetching set buildpack https://github.com/ello/heroku-buildpack-imagemagick... done
remote: -----> ImageMagick app detected

remote: tar: /tmp/build_b5b957b7efd3b0737e41460ef19a3f61/vendor: Cannot open: No such file or directory
remote: tar: Error is not recoverable: exiting now

Please help

We have the same problem. Have to clear the cache every time we deploy :/
