NewtonsoftJson

есть в репозитории, в версиях 7.0.1 и 8.0.1. Возможно, если наложить патч и использовать более новую версию, то всё соберется.

Какой Makefile тут имеется в виду?
/var/tmp/portage/dev-util/monodevelop-6.1_p2016062206/work/monodevelop-6.1/Makefile

По-хорошему тут надо бы разобраться, как добавлять в командную строку при вызове nuget ключ -verbose
о, ну там прямо команда написана: 
restore-packages:
	nuget restore


pstree -s $BASHPID
rm -rf /var/tmp/portage/dev-util/monodevelop-6.1_p2016062206 && emerge -v =monodevelop-6.1_p2016062206
