What --prefix did you use when you installed it?  Check to be sure they
are in /usr/share/icons/hicolor.  You'll also want to make sure the GTK
icon cache is updated by doing:

gtk-update-icon-cache -f /usr/share/icons/hicolor

It may be that dbus system activation is not working correctly on your
system.  Or, see below, you probably don't have the necessary config
file for nm-system-settings.

Yeah, looks like D-Bus isn't set up correctly on your system.

Same thing; the connection editor uses the icons from the applet too.
Fixing the icon cache thing will fix this too.

You may need to create it.  It provides system-level connections to
NetworkManager, which can be used before login, and across logins.  For
your case, it should probably just contain:

[main]
plugins=keyfile

and then it should work for you.

Hmm, that should already be working correctly for you, since those calls
are already protected by checks for PolicyKit version.  Do you have the
correct PolicyKit development headers
(including /usr/lib/pkgconfig/polkit.pc) installed?  What version do you
get when you run:

pkg-config --modversion polkit
