metasploit install problem

Hi All,

I am trying to install Metasploit following

Security and Networking - Installing Metasploit Framework on CentOS/RHEL 6.
http://www.darkoperator.com/msf-centosrhel


I have got to the part:

Install the pcaprun gem so we can use the portscanning modules:

     cd /opt/metasploit-framework/external/pcaprub

     ruby extconf.rb && sudo make && sudo make install


Problem: what pcaprub directory?  /opt/metasploit-framework/external is 
there, but no pcaprub subdirectory.


# ls -aF /opt/metasploit-framework/external
./  ../  burp-proxy/  ruby-kissfft/  ruby-lorcon/  ruby-lorcon2/ 
serialport/  source/

Am I missing something?

Many thanks,

-T
