It is probably Qt 5 that makes the difference.

Why did you pick it?  Ubuntu 12.04 and 12.10 comes with perfectly fine
versions of Qt 4.7.*

Yes, works here out of the box.

Dito. That one is weirder.

If we both use Rcpp 0.10.3, why do you have this and I don't?

Do the other examples (in the neighbouring directories) build?

Debug it. It broke, and you get to keep the pieces.

I support software I give away for free. I test to the best of my ability
and
resources, but keep in mind that I do not have the manpower or resource to
test on every conceivable combination of related software releases.

I really do think that you safest bet may to take the libqt* versions from
your distro.

It's all reasonable, and the only clear difference I see it qt5.0. My
releases
assume qt4.* and currently test under 4.7.
