In all honesty, you may want to think a little about this and just consider
using R from the Ubuntu repo at CRAN.  I put a fair amount of care into them,
release the day of R releases, and Michael and the mirroring typically catch
up in another day or two.

These work. Reliably. I use them on a number of machines at work.

That's an Rcpp issue, so I would have to send you back to the rcpp-devel list :)

But if I understand you correctly it works with the R binaries, which is what
I ran.  So nothing to replicate at my end.  You may need to work this out at
your end.  [ But sending code to rcpp-devel may engage someone else into
trying this for you. ]
