Error installing eventmachine 0.12.10

Created by: atoponce

Following the instructions per https://github.com/gitlabhq/gitlabhq/blob/master/doc/installation.md. This is a Debian GNU/Linux sid installation. The only place I did not follow the doc, is installing Ruby 1.9.3 p194. I used apt-get(8) instead of grabbing the tarball, seeing as though Debian Sid has the version you specify in the installation doc:

$ sudo aptitude versions ruby1.9.3
Package ruby1.9.3:
i   1.9.3.194-1

My error comes from Step 4, installing Gems. I followed the instructions for using SQLite.

$ sudo -u gitlab -H bundle install --without development test --deployment
