I'm doing a binary install from:

http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/7.1/All/xentools46-4.6.5nb2.tgz

It could be related to one of the packages on which it depends. I'm not
sure. Trying to install leads to an error state I haven't seen before,
but I think it happens because I _haven't_ installed all the basic
NetBSD installation packages (in this case the X11 ones), and as I
usually do that, I haven't ended up in this situation before.

Since this is purely a pkg related matter, you can do the following
_inside_ a lab domU. I would be weary to take things further than just
installing the packages, though ... ;-):

To repeat:

Take a blank disk(-image). Partition it and install

    base.tgz
    etc.tgz
    comp.tgz
    <kern-of-your-choice>.tgz
    man.tgz
    misc.tgz
    modules.tgz
    text.tgz

from

    http://cdn.netbsd.org/pub/NetBSD/iso/7.1/NetBSD-7.1-amd64.iso

* "Make it boot" :-)

* Set up some basic things like hostname, networking, resolver, ...

* Set and export PKG_PATH:

    http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/7.1/All

* pkg_add -v pkgin

* set /usr/pkg/etc/pkgin/repositories.conf to the above URL in PKG_PATH.

* pkgin update

* pkgin install xenkernel46

  (Just a test. This works fine.)

Now try to install xentools. Note the "warning message", and then the
situation at the end

* pkgin install xentools46

    (NOTE: The "pkg_install warnings: 13, errors: 0" message pertains
    almost exclusively to the fact that the packages at that URL are
    built for 7.0, not for the newer 7.1, which yields a "wrong
    platform" warning for every package (which I happily ignore ;-) The
    only exception is the (harmless) warning:

        pkg_add: package `ocaml-4.04.0' was already installed as dependency,
        now marked as installed manually
    )

Ummm ... Let's try again.

* pkgin install xentools46

    calculating dependencies... done.
    /usr/X11R7/lib/libpixman-1.so.2, needed by xentools46-4.6.5nb2 is not present in this system.

* pkg_info | grep -i xen
    xenkernel46-4.6.5   Xen 4.6.x Kernel
    #

Alas, not installed, apparently due to lack of X11/libpixman. If I add
the X11 packages from the NetBSD .iso image, the xentools installation
works fine.

This is in no way a showstopper, but it think it "slightly
inelegant". :-)
