I might be wrong, but this error was not there before the change of the mpl. If you have a look into the code,
the errors are shown at std::distance<> with explicit type specification. I assumed, that there migh be a conflict
with mpl::distance.

I have checked in a version with explicit std:: qualification. If it will help, it will confirm, that there is
some conflict there.
