Installing gem on FreeBSD

Recently I needed to install gollum for sake of local writing of wiki articles of my hobby project. Because I am fan of the FreeBSD operating system, I decided to describe the process for you.

To install the gem utility in FreeBSD you should use just one command:

sudo pkg install ruby24-gems rubygem-gems

After that, you will be able to use gem to install ruby gems:

sudo gem install gollum
