`exec: "gcc": executable file not found in $PATH` when compiling as a module

Compiling this little program:

package main


import (
        "fmt"
        "net/http"
)


func main() {
        x, _ := http.NewRequest("GET", "https://google.com", nil)
        fmt.Println(x)
}

in the GOPATH works fine.

But if it is compiled as a Go 1.11 module outside the GOPATH, the error:

exec: "gcc": executable file not found in $PATH

is returned. 

I know I can `CGO_ENABLED=0 go build`. I'm more curious why 'mod-ing' this package causes the change in behavior.  

Thanks all.

Hi all,

In a separate (short) forum, Russ wrote:

   "Because the pre-built packages are non-module builds and can’t be reused. Sorry. Disable cgo for now or install gcc."

I suspect these are related as well:

   #26993 -- "cmd/go: prebuilt net/http not used"

   https://github.com/golang/go/issues/26993

   #26988 -- cmd/go: GO111MODULE=on go build requires gcc 

   https://github.com/golang/go/issues/26988

But I would be curious to hear any additional commentary...
