Could not find gem 'ffi' when run simple rails template

Question

I'm getting error when try run my recept:

and run following commands:

$> rails _3.2.8_ new demo_app -T

$> cd demo_app

$> rake rails:template LOCATION=https://raw.github.com/gist/3752746/a259f4307b65493f4b7043bd78f30efa3ba6191e/test.rb

Recept is here https://raw.github.com/gist/3752746/a259f4307b65493f4b7043bd78f30efa3ba6191e/test.rb

Then i getting following error

Could not find gem 'ffi (~> 1.0.0) ruby', 
which is required by gem 'libnotify (= 0.5.9) ruby', in any of the sources.

When I use manual installation with copy-paste gems and running 'bundle install' everything works good.
What's wrong?

Try this:

require 'bundler'

# do your template gem adding stuff...

Bundler.with_clean_env do
  run 'bundle install'
end

It should be documented on the guide for making templates, right? – Macario May 29 '13 at 07:38
probably, it has been already solved. or it's just environment specific configuration when the issue appears. – itsnikolay May 29 '13 at 11:39
I've just faced this issue with a fresh new app and an app template. I'ts a non issue as long as it is documented. – Macario May 29 '13 at 21:16

i had this with a new install of a ruby on mountain lion. once you get passed it all is good. Satisfied or not, lol. – pjammer Sep 19 '12 at 23:08
Probably Mac users are happier then Linuxes'. But it still doesn't work – itsnikolay Sep 19 '12 at 23:30
Are you on a linux? i thought libnotify was for like growl on mac? could explain something at least. – pjammer Sep 19 '12 at 23:32
