Regarding my last question below, I now see that Synaptic uses dpkg, so
it seems very likely that despite the language of some of the
documentation, there is probably only one package database shared by all
the relevant tools. Enlighten me if that's incorrect.
Regarding the Entangle v0.5 I wanted to install from source, and with
the v0.4 package avaiIable via Synaptic configured for GetDeb, I ran
$ sudo apt-get build-dep entangle
to install just the dependencies for entangle, and then manually
installed one additional dependency peculiar to Entangle 0.5.
Then I used configure/make/sudo checkinstall - checkinstall being my
latest "discovery" - to install from the un-archived source in
/usr/local/src (after making myself the owner of src).
[Checkinstall runs "make install," tracks that process, then creates a
deb package based on what it tracked, then installs that package, which
results in an installation that can be cleanly removed, unlike the
unreliable "make uninstall." Nice!]
This left Synaptic showing only Entangle v0.5 (installed). It did not
show Entangle v0.4 available from GetDeb. Pleasingly clean and unconfusing.
------------------------
Perhaps with Julien Lavergne's caution in my ears, I'm wondering how to
best handle an upgrade to the already-installed libgphoto2 library
package. The upgrade is the only solution to my problem (related to
Entangle, above), and it is not yet available via repo, PPA or GetDeb.
Only from source. I want to assure that I install it as an upgrade, not
as some sort of a parallel installation which might confuse the relevant
apps, or worse, leave them using the old version.
Perhaps the archive's README and INSTALL are all the information I need,
but this is the first time I have attempted something like this, so I'd
really appreciate any special pointers that might not be covered there.

Daniel Berrange there (from Canonical) and Marcus Meissner et al at
the gphoto project have been very responsive and active in trying to
resolve a number of problems, the most recent of which have to do with
preview mode and macro mode. And they already took care of several
other major problems over the past few months.
In any case, all of these fixes have happened/are happening in
releases later than the ones available from the Ubuntu repos or even
GetDeb (though GetDeb just got back up and running after being offline
for a few months, so perhaps they are savoring that victory for a
moment before plunging ahead).
---------------------
After my first post on this topic, I have learned that, since there is
no current repo, PPA or GetDeb download, one thing I can do (in
working from source) that would be much better than simply running
"make install" would be to run checkinstall, which creates a package
and installs that, producing a clean uninstall option.
Also, spurred by Julien Lavergne's critique, I'll have a closer look
at dependency consequences.
---------------------
As I have been reading more about all this and the various available
installation-related tools, one thing currently puzzling me are
statements like these from the dpkg manpage: "dpkg keeps its record of
available packages in /var/lib/dpkg/available. ... APT has its own
system to keep track of available packages."
So in some lit it seems that there is only one package database that
all these package tools refer to and maintain. And so
https://help.ubuntu.com/community/InstallingSoftware says "read the
dpkg manual page before using dpkg, as improper use may break the
package management database." In other places two or more databases
are indicated, as in the dpkg manpage.
Can anyone clarify this with authority?

What exactly is your "camera control problem"?
