I want to share some additional steps I had to take for Reaver on the Raspberry Pi Kali install before I forget.

The Element14 WiPi is recognizing in airmon-ng and can be set to monitor mode.

But, wash was not recognized as a command.

I followed the steps found here

In addition to the libraries listed on that site I also had to install libpcap-dev as well as make (odd that make isn't installed by default).

The actions of make install took care of steps 8 and 9 of the linked tutorial.

Now that I have wash as a recognized command -- I'm pressing on with the adventure of cracking my own WPA2 via WPS
