boost :: date_time,g ++ - 4.7.0,编译错误

Question

下面的代码给出了g ++ - 4.7.0的编译错误,但是用g ++ - 4.6编译得很好.

#include <iostream>
#include <boost/date_time/local_time/local_time.hpp>
using namespace std;
int main(){
    boost::posix_time::ptime time_t_epoch(boost::gregorian::date(1970,1,1));
    cout << time_t_epoch << endl;
    return 0;
}

以下是重复出现的错误消息(编译器输出大量消息)

/usr/include/boost/date_time/local_time/local_date_time.hpp:433:84: error: use of deleted function boost::shared_ptr<boost::date_time::time_zone_base<boost::posix_time::ptime, char> >::shared_ptr(const boost::shared_ptr<boost::date_time::time_zone_base<boost::posix_time::ptime, char> >&)

我使用的是Ubuntu 12.04和libboost-date-time1.46.1.

有什么建议？
