$ bundle install

create the database.yml file that will contain the configuration parameters that will be use by framework:
$ sudo joe /opt/metasploit-framework/database.yml
 production:
   adapter: postgresql
   database: msf
   username: msf
   password:
   host: 127.0.0.1
   port: 5432
   pool: 75
   timeout: 5
 
provide the password you entered in the user creating step in the password field for the database:
$ sudo su
# sh -c "echo export MSF_DATABASE_CONFIG=/opt/metasploit-framework/database.yml" >> /etc/profile
# source /etc/profile
# exit

i did not found the pcaprub on /opt/metasploit-framework/external as the tutorial says so i use git as the git web page of pcabrub says
$ git clone git://github.com/shadowbq/pcaprub.git
$ cd /opt/metasploit-framework/external/pcaprub/
$ sudo ruby ext/pcaprub/extconf.rb
$ sudo make && sudo make install
