@titanous Thanks for the tip, I looked for it for a long time :) It is working fine.
@tianon Indeed, changing the goroot will do the trick.
@titanous as mentionned by @tianon it indeed works, but it is not suitable for development.

An other solution would be to install golang within a container and make all the development there via volumes :)
IIRC @jpetazzo did a hack the use docker in order to make some sort of virtualenv.
