When I attempt to run the 'gem install couchbase;, I get the error stack as shown below, I’ve tried it a few times, opening a new terminal, but it still doesn’t work.

Building native extensions.  This could take a while...

ERROR:  Error installing couchbase:

If you are using system ruby, you have to install fat libcouchbase library: brew install libcouchbase --universal

That did the trick! Thank you very much. (as an aside, would it be possible to add this vital detail to the official installation page?)
