There should only be a conflict if you hoist the symbols from both
libraries into the global namespace, with "using namespace mysqlpp"
and similar for Boost. The conflict should be avoidable if you remove
these "using" statements and refer to both libraries' through their
full namespaces. So: mysqlpp::DateTime instead of just DateTime.
