@certik - I could not reproduce. It works fine for me with the following profile:

extends:                                      
- file: linux.yaml                            

packages:                                                            
  launcher:                                                    
  python:                                     
    link: shared                                                   
  gcc:                                        
    version: '5.1.0'                          

This is on my laptop with Debian unstable. Also:

@johannesring thanks! In that case we can merge this. The failure is on my local computer only, it must be caused by some old systemwide packages. I'll debug it further in other issues/PRs, I think this is good to go in.
