Metasploit Ruby issues when starting from Social Engineering Toolkit

I ran into some issues with SET 6.2 and Metasploit 4.11.1 on Kali Linux 1.1.0.
SET was cloned directly from github but I had the same issue with the older version that is bundled with Kali.

Basically when selecting “Java Applet Attack Method” exploit and choosing meterpreter reverse_tcp it crashed and burned. I got the error both with Apache and the built in web server.

This is where it crashed:

[--] Tested on Windows, Linux, and OSX [--]
[*] Moving payload into cloned website.
[*] The site has been moved. SET Web Server is now listening..
[-] Launching MSF Listener...
[-] This may take a few to load MSF...
Could not find rake-10.4.2 in any of the sources
Run bundle install to install missing gems.

As this was a Ruby related issue I though that I would have a look what is up with Metasploit. I googled around and got some ideas from Rapid7 forums but none really helped, but it pointed me in the right direction.

I first tried this, but it did not help. Error messages below.

1. cd to /usr/share/metasploit-framework/
2. bundle install

root@kalle:/usr/share/metasploit-framework# bundle install

An error occured while installing pg (0.18.1), and Bundler cannot continue.
Make sure that gem install pg -v '0.18.1' succeeds before bundling.

Long story short. I had to do this. Make sure you are in the “/usr/share/metasploit-framework” dir.

1. cd /usr/share/metasploit-framework
2. apt-get install postgresql-server-dev-all
3. apt-get install libsqlite3-dev
4. gem install pg -v 0.18.1
5. bundle install

And now it works!
