I am using a raspberry pi as an air-gapped computer. Web3 installs and works just fine on my pi. My problem is I need to get a public address from a private key and this requires ethereumjs-util which will not install on my raspberry pi. I am using a pi 2 with raspbian. The following is the error log which as if by magic seems to be highlighting important parts.

Can someone please tell me what I need to do in order to install ethereumjs-util on a pi. Thanks, John
