Init issues, can't install eventmachine 1.0.7

After a first time install of Middleman on El Capitan, I attempted to use the init command. I got this message:

Could not find proper version of middleman-cli (4.1.1) in any of the sources
Run bundle install to install missing gems.

So, I ran that but tripped up on eventmachine 1.0.7.

Research reveals that this is an el capitan problem with deprecated openssl headers. I tried forcing, as suggested, with:

$ brew link openssl --force

But this did not work and I got the error message:

Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew’s openssl.
Instead, pass the full include/library paths to your compiler e.g.:

-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

Sadly, as a newbie just savvy enough to know he hates WordPress but not savvy enough to know what to do with this last suggestion, I am stuck.

I tried a number of workarounds to no avail. Does anyone know how to solve this? I am guessing a lot of newbies are giving up on MM if the first time they try the init command it fails.

Personally, I don’t use the ruby built into OS X/macOS to avoid issues compiling gems with native extensions. I use rvm myself, and there is also rbenv that is worth checking out.
