heroku-geo-buildpack Geos is not supported/available

This may be related to other recent issues that have come up. My Rails app on Heroku recently started erroring when any geometry based operation was attempted.

I've updated heroku-geo-buildpack, checked references, switched stack to cedar-14. The deployment and build process seems to work fine, but RGeo::Geos.supported? always returns false.

This is under Ruby 2.1.5. My .buildpacks file looks like:

https://github.com/cyberdelia/heroku-geo-buildpack.git#1.3
https://github.com/heroku/heroku-buildpack-ruby.git#v129

Here's the start of my deploy log (looks fine to me)

-----> Fetching custom git buildpack... done
-----> Multipack app detected

=====> Downloading Buildpack: https://github.com/heroku/heroku-buildpack-ruby.git

I have tried purging the repo cache, rebuilding, and many different forks of this buildpack that try to fix this issue, but it hasn't made any difference.

Are you able to suggest anything else to workaround or diagnose the issue?

Thank you!

Same here, but ruby 2.2.0 and cedar.

Have you tried reversing the order of the buildpacks listed in .buildpacks? i had a similar issue, with a Python stack. It seems that the multi-buildpack uses the release configuration from the buildpack listed last.
