Hi,
Sorry to forgot to provide it, i will attach it as soon i'm back of traveling (~1 march).
In the meantime i tried to compile it with "guix environment guix --ad-hoc" with partially success because i hit 2 bug
First one : ( could be skip from what i read )
http://lists.gnu.org/archive/html/bug-guix/2017-01/msg00109.html
Second one:
https://lists.gnu.org/archive/html/guix-devel/2017-07/msg00186.html
So, even if we solved my problem, i will still encounter those bugs and the second one is problematic from my point of view because it seems than the builds can't be done without to be root.
Best regards,
Yoann
