A one-time pain: You need to rebuild /everything/ that uses Rcpp as it was
all built under the assumption that there would be a shared library (on
Linux: libRcpp.so).

Starting with Rcpp 0.11.0, we can now do without libRcpp.so.  But the old
build does not know that, so it needs to be rebuilt.

See the release notes and announcement for details.
