Humm, after I applied this I got:

[acme@jouet perf]$ perf
perf: error while loading shared libraries: libbabeltrace-ctf.so.2: cannot open shared object file: No such file or directory
[acme@jouet perf]$

So it detects it somehow, builds with it, then fails to find it in the
LD_LIBRARY_PATH somehow?
