It looks like you're not using QuantLib 1.41 (the release you find at < https://github.com/lballabio/QuantLib/releases/tag/v1.41> but a checkout of the git repository, which is more recent than 1.41 and removed a few deprecated classes. If that's the case, you also need a checkout of the git repository for QuantLib-SWIG.
