I'm trying to install rmagick 2.13.1 for my legacy rails application on Ubuntu 16.04. I get following error when I do bundle install:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

What could be causing this issue?
The linker is complaining that you don't have libwebp. I don't have Ubuntu but it looks like you can install it using
sudo apt-get install webp
And then rebuild ImageMagick.
