Ok, then this looks like a project bug.  Those should probably not be
 private.
But, there is a friend declaration in class {{{Mat}}} in
 {{{math/MatrixCalc.h}}}:

 {{{
 template<typename T>
 class Mat
 {
         template<typename OT, typename Alloc> friend class MatrixCalc;
         [...]
 private:
         Mat(AbstractAllocator<T>* alloc, T const* data, int rows, int
 cols)
                 : alloc(alloc), data(data), rows(rows), cols(cols) {}
         [...]
 };
 [...]
 template<typename T, typename Alloc = mcalc::StaticPoolAllocator<T, 128,
 9> >
 class MatrixCalc
 {
         [...]
 public:
         MatrixCalc() {}

         mcalc::Mat<T> operator()(T const* data, int rows, int cols) {
                 return mcalc::Mat<T>(&m_alloc, data, rows, cols);
         }
         [...]
 };
 }}}

 This looks OK to me and also to gcc. Is this one of the
 [http://llvm.org/bugs/buglist.cgi?quicksearch=friend bugs concerning
 friend declarations in clang]?
