An error occurred while installing pcaprub (0.11.3), and Bundler cannot
continue.
Make sure that `gem install pcaprub -v '0.11.3'` succeeds before bundling.
To run MSF on Win7/32-bit, I just prepared Ruby200.
I am unable to do much without installing the bundle.
I tried to install using the following thread:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/392423
I did install a pcaprub 0.11.3.a1 (own made patch as per above url) and it works as well, but when I do "bundle install", it tries to install pcaprub 0.11.3 again!
The paths:
C:/Users/niravzaveri/Downloads/DevKit/ is set, but there's no link folder
C:/WpdPack/lib is a valid path but where its going wrong no clue.
Please let me know what other information would you need to help me solve the issue.
This is my first encounter with Ruby.
Thanks for the help!
