Antony, can you make that happen for us this week?

That'd be awesome.
Perhaps we can even "backport" the fixes, thus sorting out the build problems for the current MariaDB 5.5 stuff.

It might be handy if we were to inventorise which Boost version each build platform has, and put that in a table so we can just keep it in mind. (i.e. RHEL5, RHEL6, Ubuntu 11.10, and so on). Whatever platforms MariaDB gets built for.

Well we used to have all of Boost in the tree, but it made the MariaDB people quite unhappy as all of Boost is a huge pile of tiny files. "only the bits we need" sounds awesome, but I'm not sure the Boost include structure makes that possible - if you can do it, then that's definitely something we can show in a suggested merge.
But otherwise, probably best to just make sure that OQGRAPH builds properly with the Boost versions that are out there.

Yes, "new BSD" (without advertising clause) can be included with pretty much anything including proprietary licenses.
Whether the source files are shipped with others is fairly irrelevant, the main issue with licensing is in linked binaries, whether it's allowed to link to begin with and what rights the people downstream (direct and possibly indirect) have to the sourcecode.

Anyway, the short answer is "yes", using either a BSD library (BSD licensed source files) in a GPL project is fine.


Cheers,
Arjen.
