>Description:
If one disables the "dbus" option, "print/evince3" fails during
creation of binary packages because the "lib/systemd/user/evince.service"
file can't be found.

Files like this are common elements for "dbus" and looking at the
"options.mk" and PLIST, a few others were conditionalized on
"${PLIST.dbus}".

The same should be done for the file noted above.
>How-To-Repeat:
PKG_DEFAULT_OPTIONS+= -dbus
or
PKG_OPTIONS.evince+= -dbus

Attempt to package print/evince3.
>Fix:
Apply the following patch:
