No. Distribution packages usually lag behind the project upstream.
Ubuntu 12.04 has been released last year, and their policy don't allow them to
update the packages within this specific distribution version.
This is why you run into trouble when you try to mix distribution packages
(from last year) with the current development head.
Don't mix packages from distributions with packages built from sources when
version dependencies don't match. All the required dependency information is
found in the README files of each project.

But I'm not mixing old packages with new: I tried fetching everything from
git.lttng.org. The README for lttng-ust reads in part:
PREREQUISITES:
- liburcu
Userspace RCU library, by Mathieu Desnoyers and Paul E. McKenney
-> This release depends on liburcu v0.7.2
* Debian/Ubuntu package: liburcu-dev
* Website: http://lttng.org/urcu
* Releases: http://lttng.org/files/urcu
* GitWeb:
http://lttng.org/cgi-bin/gitweb.cgi?p=userspace-rcu.git;a=summary
* Git: git://lttng.org/userspace-rcu.git
Doesn't this say that I can get the required liburcu from git.lttng.org's
userspace-rcu? Could it be version 0.7.6 is not retro-compatible with 0.7.2
(that is to say, lttng-ust requires 0.7.2, and 0.7.2 only, not "0.7.2 or
later")?
