Is there a question to go with this?

RMagick isn't compatible with the latest version of rails. The gem hasn't been updated for sometime.

The OP is having an issue with the installation of the gem, which in itself has absolutely nothing to do with Rails of any version. Besides that, rmagick is compatible with Rails 4.

The current repository is at https://github.com/gemhome/rmagick and all tickets should be placed there.
