Hi, As specified in the TODO, it was needed to replaced automagic networkmanager check in the configure script by an optionnal support, i replaced it by a AC_ARG_ENABLE call. You'll can find in attachment a git format-patch which normally solves the problem, update the ebuild (added networkmanager USE flag and apply patch), and Manifest too. mrpouet Reproducible: Always
Created attachment 188270 [details, diff] the patch which solves the problem
merged and pushed to overlay. Thanks for reporting and don't forget to report upstream as well.
upstream opened http://bugzilla.gnome.org/show_bug.cgi?id=578951 ;)
