OQGraph is missing from 5.5 bintars (and debs)

OQGraph in 5.3 needs boost 1.40 or later, otherwise it's not built.
In 5.5 it needs boost 1.45.
We have 1.42 on all our package-building VMs.

As a result, all 5.5. binary packages don't have OQGraph.

VMs need to be updated to have the newer boost.

See http://kb.askmonty.org/en/installing-the-boost-library-needed-for-the-oqgraph-storage-engine

When upgrading boost, update the above KB page too.

OQGraph fails to compile with a new Boost. We're waiting for Anthony to fix it.
