Yes, "-v" is equivalent to "-d 2", according to the man page.

If you have a *.deb or *.rpm based packaging system, start with 
an X11 package that claims to be a "base" or "common" package.
You might find that this will be enough to get xterm going as
a test client program.  You'll also need xauth, because sshd
tries to exec(3) it, but that would probably come in the base
X package.  Debian will try to throw a bunch of "recommended"
packages at you, which you'll have to manually deselect if you're
looking for a bare-minimum client install, I think. 

The following lists what libraries xterm requires on my 
system, so it could help you while you're looking through
packages.  

evol:/etc/ssh2# ldd `which xterm`
        libXaw.so.6 => /usr/X11R6/lib/libXaw.so.6 (0x40019000)
        libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x40051000)
        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40063000)
        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x400ab000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x400b5000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x400cb000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x400d7000)
        libncurses.so.4 => /lib/libncurses.so.4 (0x40176000)
        libc.so.6 => /lib/libc.so.6 (0x401c4000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

The good news is that sshd probably won't need to be rebuilt
with X support.
