I just did it again with cut and paste from above.
Now the end of make.conf is (from cut and paste)
FEATURES=" buildsyspkg"
USE="-networkmanager"
and I still get
newlap gottlieb # emerge --depclean networkmanager
Calculating dependencies... done!
net-misc/networkmanager-0.9.8.2 pulled in by:
gnome-base/gnome-control-center-3.6.3-r1 requires
>=net-misc/networkmanager-0.8.997
gnome-base/gnome-shell-3.6.3.1 requires
>=net-misc/networkmanager-0.8.999[introspection]
gnome-extra/nm-applet-0.9.6.4-r1 requires >=net-misc/networkmanager-0.9.6
net-libs/libsocialweb-0.25.21 requires net-misc/networkmanager
To be sure that make.conf was being consulted, I tried it with a
fictitious flag joeee, which "worked" and then with -joeee which "didn't
work". That is, putting -joeee in make.conf results in *neither* joeee
or -joeee in the USE printed by emerge --info

My wording here was bad. I meant that networkmanager was not in the USE
shown by emerge --sync and apparently (to my surprise) specifying
-foo in make.conf only removes USEs from the emerge --sync listing
and does not insert -foo into the emerge --sync USE, assuming
that neither foo nor -foo was originally in emerge --sync USE.
I am sure I am doing something wrong since I agree that
USE="-networkmanager"
in make.conf should be just what is needed, but I don't think it is just
my misspelling networkmanager.
