For windows users who run into this, and are 100% psotive that they have the devkit installed:

When installing, you will be presented this prompt

Choosing 1 is not enough. Just press enter (1 & 3) and that will install the devkit properly.

For Mac with Brew, simply..

brew install imagemagick

Then gem install imagemagick will work smoothly.
