libvisio error

[echothevoid]

Hello!

I  got an error after running regular sudo port upgrade outdated command.
The log tells me that:
:info:build /opt/local/include/boost/thread/detail/move.hpp:31:10: fatal
error: 'type_traits' file not found
I have found a similar issue on:
http://stackoverflow.com/questions/14104298/clang-boostspirit-and-c11 but do
not know how to fix it in the macport's way.
I am using 10.7.5 Lion, with Xcode version 4.6.3.
The outcome of: 
port installed | grep gcc
  gcc49 @4.9.3_0 (active)
  gcc_select @0.1_8 (active)
  libgcc @5.2.0_0 (active)

Can you suggest a newbie like me what to do next?

Many thanks,
void
