Yes, sorry, known issues. We need to get RcppArmadillo 0.2.0 out ASAP but are
finishing some documentation -- please grab it from svn right now (or take a
tarball from R-Forge).

|     I ran into a similar error today after I upgraded my version of Rcpp
|     from 0.7.10 (or maybe 0.7.10.1) to 0.7.11:
|     /opt/R-2.10.1/lib/R/library/RcppArmadillo/libs/RcppArmadillo.so:
|     undefined symbol:
|     _ZN4Rcpp8internal12set_list_eltINS_5NamedEEEbP7SEXPRECS4_iRKT_
| 
|     In my case, uninstalling RcppArmadillo and then installing it again fixed
|     the error.
| 
|     Maybe a new package version scheme is necessary to make it easier to
|     keep RcppArmadillo and Rcpp in sync? Would bumping up version numbers
|     more when there is a breaking API change help? For instance, when Named
|     was eliminated between 0.7.10 and 0.7.11, the new version could have
|     been called 0.8. RcppArmadillo packages would then depend on the Rccp
|     version being less than the next major API change.
