The Hypermedia Bloodhound depends on libpcap, so if you are on linux, you need to install the package first (sudo apt-get install libpcap-dev), if you are on OSX 10.6+, you already have it.

We also depends on libgeoip for the IP address lookups, so sudo apt-get install libgeoip or brew install libgeoip on OSX.

$ npm install $ sudo node bin/bloodhound 

$ node bin/bloodhound --help
