Hi Dan,

Thanks for switching to the list.

I think I just had that yesterday at work -- you do have to be careful to use
_matching_ RInside and Rcpp releases.  Which I why going with CRAN is a good
option.

Using the _released_ versions 0.7.11 for Rcpp and 0.2.2 for RInside should
'just work'.   As Romain said, please send along the version numbers you used.

We do try to make pretty sure that this works for _released_ versions. 

Rcpp tends to change a lot so there sometimes is something changing at its
side that may not yet be reflected at the RInside side. We try to minimise
that but it happens. Sticking with the releases should help as a remedy.

Thanks, Dirk
