>Description:
I often need to run pkg install -fR (something) to properly deal with library issues according to UPDATING.  What I noticed a few times recently is pkg install -fR will Reinstall or Upgrade packages but it doesn't seem to Install newly required deps, thus it fails part way through with something like:

Reinstalling xorg-server-1.7.7_6,1 done
Reinstalling libsoup-gnome-2.34.3_2 done
Reinstalling gnome-mount-0.8_10 done
Reinstalling gvfs-1.6.6_3missing dependency tdb-1.2.11,1root at trident:/root # 

If I run pkg install tdb, it gets around the problem and then I can re-run pkg install -fR to finish where it left off.  But I have to do it for exiv2 as well.  Also the missing newlines make the error harder to see.

If I run pkg upgrade -n before I do the pkg install -fR, it shows me the newly required dep packages among the Upgrading ones:

..
        Upgrading talloc: 2.0.7 -> 2.0.8
        Installing tdb: 1.2.11,1
        Installing exiv2: 0.23,1
        Installing xconsole: 1.0.5
..

Is this intentional, or something that should be fixed, or needs more information/discussion?  Should I file a PRI could probably get around it by doing pkg upgrade first, but then the system will be doing more work.  I can reproduce this issue.  Thanks.
>How-To-Repeat:
Follow UPDATING instructions to force reinstall all deps of some packages like libffi, icu, boost-libs.  The pkg install -fR might miss some newly needed deps like tdb, exiv2.
>Fix:
"pkg install -fR" should automatically pull in new deps like "pkg upgrade" does, or it should abort with a helpful error message before upgrading a portion of  packages then exiting.
