[Boost-users] share_ptr and Container compilation error on new version

Hello all,
I'm trying to build an application. This isn't an app that I wrote but 
rather inherited. I'm currently porting it from Fedora 15 to Fedora 20. 
It compiled well on gcc 4.6.3 with boost 1.46.0. However, Fedora 20 has 
gcc 4.8.3 and boost 1.54. I'm new to boost and have never used it before 
but it looks very comprehensive. As far as I know boost/shared_ptr is 
the only header this component of the application is including. I'm 
wondering if boost changes might be causing this or maybe gcc changes 
but it's difficult to tell from the documentation and I'm a little under 
the gun at the moment.

This code:

template<typename Container>
class DefinableVectorFinalizer: public XmlFinalizer
{
typedef typename Container::value_type contained_value_type;
typedef typename Container::value_type::value_type value_type;
....
}

g++ is throwing this error which seems to have some sort of problem with 
Container::value_type::value_type:

../../../../../devel/include/xcl/io/DefinableVectorFinalizer.h:31:54: 
error: no type named ‘value_type’ in 
‘xclApp::DefinableVector<boost::shared_ptr<simApp::Project> 
 >::value_type {aka class boost::shared_ptr<mainApp::Project>}’
typedef typename Container::value_type::value_type value_type;

xclApp::DefinableVector looks like this:
class DefinableVector
{
public:
typedef typename std::vector<T>::size_type size_type;
typedef typename std::vector<T>::value_type value_type;

typedef value_type& reference;
typedef const value_type& const_reference;

typedef typename std::vector<T>::iterator iterator;
typedef typename std::vector<T>::const_iterator const_iterator;
....
}

Any insight into this would be hugely appreciated!!!
