> did you run ldconfig on the machine without lttng-modules ?

   Not the first time, I must admit.  I had forgotten, silly me.  That was why I had to use LD_LIBRARY_PATH or LD_PRELOAD.  With ldconfig done, there is no need to do so.

> does this machine recognise libraries in /usr/local automatically (see /etc/ld.so.conf) ?

   Yes, Ubuntu has /etc/ld.so.conf "include /etc/ld.so.conf.d/*.conf", and that includes libc.conf "/usr/local/lib".

> lttng-modules is completely unrelated to user-space tracing.

   Indeed, I just wanted to prove it by trial.  (It also allowed me to make sure "make uninstall" worked properly)
