Pitch compensation on speed effect doesn't seem to work

[Alistair Riddoch]

I was really happy to see this commit a couple of days ago:

402c251eae642ff3352bb4b8895ee882503eddfc
Add pitch compensation to speed effect (requires MLT git)

My videos depend on having pitch compensated audio for time accelerated
video, and the only way I've been able to do it is by exporting the audio,
and modifying the tempo in Audacity. I'm really thankful this has been
added, but I don't seem to be able to get it to work. The audio pitch is
not affected by the setting.

I've rebuilt mlt from git master, verifying that bmatherly/pitch_compensate
is included.
I've rebuilt kdenlive from git master, completely from a clean tree.

What could I be missing, and what more information is needed to work out
why?
