>Description:
import ( 
        ?http://github.com/blahblahblah/osutil? 
) 
osutil.Myfunc() 

This throws an ?undefined? error for osutil.Myfunc(), although Myfunc is defined inside $GOPATH/src/github.com/blahblahblah/osutil/somefile.go
I had to copy the entire function to that file to make it work.

NB: It works in linux.
>How-To-Repeat:
install the go package from:
http://nycdn.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/7.1/All/go-1.8.3.tgz

set GOPATH env variable.

go get <Any github repository of your choice.>

Then type go build inside the desired package folder.

NB: The github repository of your choice must contain a go file that imports something from another package downloaded from github.
