Is it there an easy way to run or fix this? thanks.

This usually happens if either CGO_ENABLED env var is set to 0 or C compiler is missing. CGO_ENABLED is 1 by default, but maybe something overrides it on your system - f.e. here is how I can simulate the same errors on my Mac: 

❯ CGO_ENABLED=0 go run main.go

Setting CGO_ENABLED=1 resolves the above errors. Please see this doc for more details: https://github.com/prebid/prebid-server/tree/master/docs/build
