Title: Fix Ardour 3 

Pinning the version of boost to 1.49 because compilation fails with 1.5:

I don't know where to look to try to fix this, perhaps it is a problem upstream, but this is a beta version of Ardour anyway so I think it's OK to wait until there is a release to see if we need to investigate further.
