I have the same problem on OSX 10.11.1

[phirestalker]

I was able to get it to install by replacing d with '/usr' on line 46 of setup.py, like this:

lib_sub_dirs = [os.path.join('/usr', sub_dir) \

I can't guarantee it will work on all systems as it is a quick and dirty hack, but there you go

Pip is using the wrong pcap header. Install libpcap-dev will fix this issue in ubuntu.
