I'm guessing you have a rather old version of lttng-modules?  The "ltt-"
prefix was replaced with "lttng-" about three years ago:

commit a90917c3f8c4
Author: Mathieu Desnoyers <mathieu.desnoyers at efficios.com>
Date:   Sun Jan 22 16:13:41 2012 -0500

    Mass rename: ltt_*/ltt-* to LTTNG_*/LTTNG-*

$ git describe --all  a90917c3f8c4
tags/v2.0-pre11-5-ga90917c3f8c4

Make sure you're not inadvertently using an old unsupported 0.x version
of the modules.
