Thanks for following up.  I actually did grep through your sources when I
checked that it did in fact work just fine on Linux.  

And as mzR does not use the symbol, I think we are victims of a mild compiler
or linker error here: The symbol was there (defined static, but, IIRC,
private) and is no more.  

So the internals changed, but the interface did not. A rebuild should
certainly help.

If there is something else we ought to do on the Rcpp side, let me know.

Dirk

PS Shall we talk to some of the BioC folks?

It is possible that since Rcpp API changed, the missing symbol is detected by the dynamic link loader and so aborts loading mzR. (Not sure why it would work on some platforms and not others -- maybe dynamic linking is more tolerant than on others.)
