title: godep: exec: "go": executable file not found in $PATH
body: <p>I trying to deploy my server on heroku and I stuck on step where I should use godep, I spent little time with GO, last two days I had looking how to solve this issue, actually it's a popular issue, but I can't figure out, maybe I did something fundamentally wrong.</p>
  
  <p>I have OS X 10.11.2<br>
  My GOPATH  - Users/denis/Programming/Golang<br>
  My PATH - $GOPATH/bin<br>
  I trying to use godep to my project which is placed in $GOPATH/src/backend</p>
  
  <p>in my PATH I have an executable godep file(not .go).</p>
  
  <p>Whole structure of my workplace.</p>
  
  <pre><code>/Golang/
       .bin/
          godep //executable file
       .pkg/
          .darwin-amd64/
               .//other folders/
       .src/
