You need a C compiler:

xcode-select --install

[christianwoehrle]

the c compiler was already installed with the mentioned command ( a few days ago).
Trying to install it again leads to that

cwoehrle$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

[aarzilli]

Then for some reason your go install is configured not to use it. Try go env it should tell you CGO_ENABLED=1.

[christianwoehrle]

that´s it, it works with CGO_ENABLED=1.
thank you very much!

It still fails to install on a fully up-to-date Homebrew and macOS.
