If you have the PPA's deb-src line in your sources.list [1], you can use
"apt-get source" to download the source packages, including the debian/
subdirectory where the packaging configuration is stored.

For example:
apt-get source tcf-lttng-agent

will download the source package for the lttng-agent plugin in the
current directory (no need to be root). You can then cd into the new
directory that was created and use "dpkg-buildpackage" to rebuild the .deb .


Since the tcf and tcf-plugins packages are based off git or svn
checkouts, the version number includes the date at which the checkout
was done.

And yes, as noted on the PPA's page, the tcf plugins currently don't
work with UST 0.12 (But the "kernel" provider should still work). As
soon as a new working version is released / announced, I'll update the
package and add a Natty build.


[1] For example for Lucid it would be:
deb-src http://ppa.launchpad.net/lttng/ppa/ubuntu lucid main
