Hi, I’ve been trying to deploy my app to heroku. Once for a while the app will start, but most of the time it crashes with the following error:

I tried cleaning the deps, getting them and compiling manually, but this is what I ended up with:

Please make sure that you are using Erlang / OTP version 18.0 or later
and that you have a C compiler installed.
Please follow the directions below for the operating system you are
using:
Mac OS X: You need to have gcc and make installed. Try running the
commands `gcc --version` and / or `make --version`. If these programs
are not installed, you will be prompted to install them.
Linux: You need to have gcc and make installed. If you are using
Ubuntu or any other Debian-based system, install the packages
`build-essential`. Also install `erlang-dev` package if not
included in your Erlang/OTP version.
See https://github.com/riverrun/comeonin/wiki/Requirements for more
information.
If you have any ideas on how I could fix this, I’d be really glad to hear them. Thanks!
