I've fallen over this a few times. It happens when you have multiple
R sessions running, and R tries to update Rcpp while it is loaded in
the other session.
For example, I'm working on one
This might be a good opportunity for developing some error classes for
signaling these errors that can be used to programmatically do
something more useful at the library/require. I can try to help with
that.

Hi R-devel,
One of the more common issues that new R users see, and become stumped
by, is error messages during package load of the form:
> library(ggplot2)
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()),
versionCheck = vI[[j]]) :
there is no package called 'Rcpp'
Error: package
