Boost 1.50 has introduced an issue whereby building wtdbo fails with a linker error.

Linking CXX shared library libwtdbo.dylib
Undefined symbols for architecture x86_64:
  "boost::system::system_category()", referenced from:
      void boost::condition_variable_any::wait<boost::mutex>(boost::mutex&) in FixedSqlConnectionPool.o
      boost::mutex::lock() in FixedSqlConnectionPool.o
      boost::unique_lock<boost::mutex>::lock() in FixedSqlConnectionPool.o
      boost::condition_variable_any::condition_variable_any() in FixedSqlConnectionPool.o
      boost::mutex::mutex() in FixedSqlConnectionPool.o
      __GLOBAL__I_a in FixedSqlConnectionPool.o
  "boost::system::generic_category()", referenced from:
      __GLOBAL__I_a in FixedSqlConnectionPool.o
ld: symbol(s) not found for architecture x86_64

To solve this we need to link wtdbo with boost_system. I'd provide a patch but I don't know CMake. :)

This build was on OS X with Boost 1.50 but I imagine it affects all operating systems.
