TL;DR: update your library.

It seems that you are using a package (lubridate) compiled against the
most recent Rcpp release, but you are trying to load it using an old
version of Rcpp. We try hard to smooth things out so that the
transition "forward" (i.e., updating Rcpp) is as painless as possible.
In fact, the recent v1.0.7 landed on CRAN with 2.3k+ reverse depends
and only a couple of issues that got resolved with a rebuild. This is
the inverse situation: the rest of the packages are updated (built
against the newest Rcpp), but the local Rcpp version is an old one.
This is not supported and cannot be supported; otherwise, our hands
would be tied to make any progress or innovation.
