Gitlab rake gitlab:check fails on Mountain Lion Server - ruby-on-rails

Question

I'm trying to install Gitlab on an 10.8.2 Server but when I execute
bundle exec rake gitlab:check RAILS_ENV=production
I'm getting the following error.
Checking Environment ...
gitlab user is in gitg group? ... yes
Has no "-e" in ~gitolite/.profile ... yes
Git configured for gitlab user? ... yes
Has python2? ... yes
python2 is supported version? ... yes
Checking Environment ... Finished
** Invoke gitlab:gitolite:check (first_time)
** Invoke environment
** Execute gitlab:gitolite:check
Checking Gitolite ...
Using recommended version ... no
Try fixing it:
We strongly recommend using the version pointed out in the installation guide.
For more information see:
doc/install/installation.md in section "Gitolite"
Repo umask is 0007 in .gitolite.rc? ... yes
Allow all Git config keys in .gitolite.rc ... yes
Config directory exists? ... yes

I literally checked the permissions a thousand time, if anyone can get me a hint on the problem this would be great.

This seems to be an issue in progress: see Issue 2890.
The commit e0d62d9c might fix this problem, in lib/tasks/gitlab/task_helpers.rake.
def gid_for(group_name)
- group_line = File.read("/etc/group").lines.select{|l| l.start_with?("#{group_name}:")}.first
- group_line.split(":")[2].to_i
+ Etc.getgrnam(group_name).gid
end
