[philo_neo71]

Hi,
My configuration is like this : Raspberry PI3, ARMv6 at 1200 Mherzts, 1giga of Ram and SDcard is UHS class 1, 32 giga bits, network switched !
I use Netbsd 7.0 with pkgsrc2016Q1, i have compiled xfce4 for window manager.
I've problems with the browsers :
1/ for firefox The last pkgsrc is 2014Q3 and it contains (pkgsrc2016Q1) no firefox packages.
2/ Opera ask me the licence of opensource , i don't understand. How can i do for licence activate.
3/ Epiphany issue after the commands : make deinstall, make clean-depends clean, make reinstall; this is my output :
