Rich, I know that you've stated in the past that you don't do 'install'
and
refer to the run scripts and the README file in response to problems
installing libguestfs on Ubuntu.
Should an install of libguestfs be considered as a "do at your own
risk" endeavor?
Putting it in the quasi-support realm?
And is the appliance trying to find libcap.so on the host or within
the appliance when it fails?

It should work, but it's not necessary, and it may have bad effects.
It will pollute your filesystem with files which are not managed by
dpkg (making them effectively impossible to remove). It will likely
conflict in strange ways with the real libguestfs dpkg.
The easier way is just to use the ./run script in the libguestfs
directory, eg:
./run ./fish/guestfish [etc]
Note that 'make quickcheck', 'make check' etc implicitly uses the
./run script.
And is the appliance trying to find libcap.so on the host or within
the appliance when it fails?
The problem above is that libcap.so.2 isn't being copied into the
appliance. There could be several reasons for this:
(1) Most likely, what is installed on your host doesn't match what is
listed in /etc/apt/sources.list; eg. libcap might have recently had an
soname bump in Ubuntu and you haven't yet installed the new version on
the host (but febootstrap picked up the new version for the
appliance). Just doing an 'apt-get dist-upgrade' should fix it.
(2) You're mixing the appliance from another installed libguestfs with
the appliance from the libguestfs you built locally. This doesn't
appear to be the case, from the full output you gave.
(3) Did ./configure pick up that libcap is installed? Did it link
guestfsd with -lcap? Did you then uninstall libcap on the host? Did
febootstrap download libcap during the build?
(4) There's some problem with the dpkg metadata.
(5) There's some bug in febootstrap or the dpkg/apt utilities that it
depends on.
#4 and #5 can be diagnosed by carefully looking at whatever is being
generated in '/usr/local/lib/guestfs/supermin.d/hostfiles', while at
the same time reading this:
http://libguestfs.org/febootstrap.8.html#supermin_appliances
You can also avoid building the appliance at all by using the fixed
appliance:

I had similar problems while preparing 1.20 on Debian/unstable, but I
fixed this for the package that I uploaded. (It's still stuck in the NEW
queue: http://ftp-master.debian.org/new/libguestfs_1:1.20.1-2.html)
Somehow I forgot to send the necessary patches to the list. Will do
tonight.
Cheers,
