 Hi,

 I am compiling Boost.Python with '''nvcc/6.5''', '''gcc/4.6.2''',
 '''python/2.7.8''' and '''cmake/3.0.1''' right now.

 As a side note, I modified the standard ''FindPythonLibs.cmake'' a bit to
 match the ''cuda_add_library calls''.

 During compile, I get the error

 {{{
 boost/python/object_core.hpp(499): error: function
 "boost::python::api::object_operators<U>::attr(const char *) const"
 returns incomplete type "boost::python::api::const_object_attribute"
 }}}

 from ''include/boost/python/object_core.hpp''
 {{{
 template <typename U>
 template <class T>
 object api::object_operators<U>::contains(T const& key) const
 {
     return this->attr("__contains__")(object(key));
 }
 }}}

 Replacing the return statement with
 {{{
     return (*this)[object(key)];
 }}}
 seems to compile and my modules work, but I am not sure if the
 functionality is still ok since I have no idea what this function actually
 does (nor how to test/trigger it).

 It would be great if we can fix that compile error and someone could give
 me a review.
