It is relatively pretty easy to build R from source, maybe that would be
alternative. But you could simply jump three years forward: you have a
reasonably current compiler, so why stick with a seriously outdated R ? We
are R 3.2.4 now with R 3.3.0 scheduled to release next month.

Same motivation as your use of 'module load' on the cluster: to dynamically
load components.
Glad you have it working, but this is no longer an Rcpp discussion so might
be best to take this elsewhere...
