Forte compiler template error

Hi, I was trying to use the tokeniser lib and encountered this error: "/home/patwarta/boost_1_28_0/boost/iterator_adaptors.hpp", line 819: Error: The base "boost::detail::iterator_adaptor_traits_gen, std::basic_string, const std::basic_string&, const std::basic_string*, std::forward_iterator_tag, int>::type" must be a previously defined class or struct. "XMLbParserWrapper.cxx", line 11: Where: While specializing "boost::iterator_adaptor, boost::detail::tokenizer_policy, boost::char_delimiters_separator>, std::basic_string, const std::basic_string&, const std::basic_string*, std::forward_iterator_tag, int> Any ideas? Thanks in advance, Tanmay
