Demangling the names of the symbols that are not present produces

on a Linux system (I don't have access to an OS X system).

I guess I would start by trying to install Rcpp from sources. The order seems to be backwards in that the new version of RcppEigen should be installed before the minqa version. I would try the order Rcpp, RcppEigen then minqa.

Installing in the order you suggested works! :O)

Installing Rcpp from sources also helped when I was trying to install rmr2 (R & Hadoop lib) and was getting the very same "Symbol not found" message.
So thanks for this little info! Saved my day!
