Answer 1

This method is for Rails 3.1.0 (and hopefully up) on 64 bit machine. I used on Ruby-1.9.2-p180.

Basically, the method above: $ sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

may work, but without bundler.

To do it with bundler, first must run this on terminal:

bundle config build.mysql2 --with-mysql-config=/usr/local/mysql/bin/mysql_config

Note "mysql2" not "mysql" as shown in that blog.

That adds a config to ~/.bundle/config file

Then add this to ~/.bash_profile:

export ARCHFLAGS="-arch x86_64"

That is the same with telling bundler to run the command on top of this post.
