Robin,
this is unlikely a Mac issue, merely newer compilers give you better error
handling pointing to issues in the code that may not have been detected before.
If you post the code we can have a look.
Also check your tools - the RcppArmadillo error points out that your compiler
setup is broken since it cannot create runnable executable. Check config.log
for details.
Cheers,
Simon
