Set $GOROOT variable with homebrew

If you are using go with homebrew on OSX, add this to your ~/.profile to set the $GOPATH automagically:

GOVERSION=$(brew list go | head -n 1 | cut -d '/' -f 6)
export GOROOT=$(brew --prefix)/Cellar/go/$GOVERSION/libexec

• Update:

Added libexec, as suggested by @solidfox in the comments.

• Update 2:

Setting the GOROOT variable should not be necessary in newer versions of go. If you really want to, use:

export GOROOT=$(go env GOROOT)
