posix-spawn issue on FreeBSD - freebsd

Question

I was running GitLab 5.2 I believe on FreeBSD 9.1-RELEASE for months and things were going well, no obvious issues I could see.
I've recently upgraded to 6.0 following the guide provided on gitlab.org, unfortunately I'm now getting errors like the following:
No such file or directory - posix_spawnp

I'm definately not an expert but I'm not sure if FreeBSD offers any posix compatibility. I've manually installed the posix-spawn gem but it made no difference. I was unable to find help through my searching, the only similar cases I could see came down to missing pygments but I have that installed.
Is it not possible to use GitLab on FreeBSD with the later versions? I see that the unofficial FreeBSD/GitLab install guides are only for 5.1 and 5.2 so that might be an indication. It would be a shame if this is so, GitLab is a great piece of software and I hate to have to drop it.
Appreciate some insights, thanks

Make sure the correct path to git is set in gitlab/config/gitlab.yml as FreeBSD installs ports/packages to /usr/local by default:
git:
bin_path: /usr/local/bin/git
Then restart GitLab.
How to debug this:
Print the vars of the function in to gitlab/vendor/bundle/ruby/1.9/gems/posix-spawn-0.3.6/lib/posix/spawn.rb on line 187 (adjust if needed):
puts "DEBUG"
puts env
puts argv
puts options
_pspawn(env, argv, options)
Run Application Status:
# bundle exec rake gitlab:check RAILS_ENV=production
{}
[["/usr/bin/git", "/usr/bin/git"], "--git-dir=/home/git/repositories/root/git-playground-project.git", "rev-parse", "HEAD"]
{:in=>#<IO:fd 13>, #<IO:fd 14>=>:close, :out=>#<IO:fd 16>, #<IO:fd 15>=>:close, :err=>#<IO:fd 18>, #<IO:fd 17>=>:close}
Find the debug lines and verify the parameters.
Good luck!
