Cannot install passenger with Nginx

I have a rack application that I want to migrate from Ruby 1.8.7 + Apache + passenger to Ruby 1.9.1 + Nginx + passenger.

I have made up the following script for a quick install all in one, and it raises an error...

Here is the installation script: (basic one with all the steps I need to install everything on a Ubuntu 10.04 Lucid Lynx fresh box)

Nginx sources

cd /tmp
wget http://nginx.org/download/nginx-0.7.66.tar.gz
tar xzf nginx-0.7.66.tar.gz
cd nginx-0.7.66

openssl required for SSL/TLS

sudo apt-get install openssl
sudo apt-get install libssl-dev

Compilation stuff

sudo apt-get zlib1g-dev

Ruby interpreter 1.9.1

sudo apt-get install ruby1.9.1 ruby1.9.1-dev rubygems1.9.1 irb1.9.1 \
ri1.9.1 rdoc1.9.1 build-essential nginx libopenssl-ruby1.9.1

Make sure default ruby uses version 1.9.1

sudo update-alternatives --install /usr/bin/ruby ruby /usr/bin/ruby1.9.1 400 --slave /usr/share/man/man1/ruby.1.gz ruby.1.gz /usr/share/man/man1/ruby1.9.1.1.gz --slave /usr/bin/ri ri /usr/bin/ri1.9.1 --slave /usr/bin/irb irb /usr/bin/irb1.9.1 --slave /usr/bin/rdoc rdoc /usr/bin/rdoc1.9.1
sudo update-alternatives --config ruby

Passenger (rake-0.8.7, fastthread-1.0.7, rack-1.1.0, passenger-2.2.14)

sudo gem install passenger

Activate Passenger in nginx, select option 2 to use nginx sources donwloaded above

cd /var/lib/gems/1.9.1/gems/passenger-2.2.14/bin
sudo ./passenger-install-nginx-module

And this is the error message I got:

It looks like something went wrong
Please read our Users guide for troubleshooting tips:
/var/lib/gems/1.9.1/gems/passenger-2.2.14/doc/Users guide Nginx.html

I do not understand the reason of this error. Is this a compatibility problem?
Hope you have any clues :)
