Manually update a library? And a GetDeb question?

[John Hupp]

Running Entangle (www.entangle-photo.org) to do remote capture (aka 
"tethered shooting"), which uses gphoto2 as the backend.  Developer 
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?
