   Ah yes, the Ubuntu LTTng ppa...My problem with that installation is that it
provides no source code and even less compilation instructions, so I can't tell
how it was built nor reproduce it from the LTTng git repositories.  It does
report a "ust" provider which I haven't tested ---are you saying the ust side
does not work?  Wouldn't surprise me much, as it's been broken since UST 0.9.

   Don't worry about my download problems: they're nobody's fault but our
paranoid headquarters'.  We work around it.

   If updates-nightly isn't up to speed yet, I suppose
http://download.eclipse.org/technology/linuxtools/update is even worse?

   Why is it the http://git.eclipse.org/c/linuxtools/org.eclipse.linuxtools.git/
website doesn't allow snapshots? Without the snapshot facility, I don't see how
I can checkout the code short of going through the tree and downloading each
file in turn, a dreadful prospect. What am I missing?

   At this point you're saying the eclipse LinuxTools nightly updates
(http://download.eclipse.org/technology/linuxtools/updates-nightly/) do not
contain the right version (so going through that eclipse repository is out of
the question for now), leaving just the git repository
(http://git.eclipse.org/c/linuxtools/org.eclipse.linuxtools.git/)...Which I
can't figure out how to check the (correct) code out from.  I'm stuck for now,
it seems.
