I am confused.  So in general no error on Linux and on some versions of
Windows and OS X, but an error on other versions of OS X and Windows?

Could this be as simple as required a rebuild of the related packaged (eg
Rcpp and mzR) ?

>From what I recall I simply followed a warning from g++ about an unused var
which I commented out in src/Evaluator.cpp.  You could always fetch an older
src/Evaluator.cpp and drop it in and see what happens.

We'd need something reproducible, preferable on a platform I have access too.
