Looks like because shiboken uses libxslt, which uses libxml2, which uses icu, which now requires C++11, shiboken will require C++11 too. To indicate that requirement, put this into the Portfile:

compiler.cxx_standard 2011

Probably this will be needed too:

configure.cxxflags-append -std=c++11

You can ignore the other error in that logfile:

/opt/local/include/sparsehash/dense_hash_map:106:10: fatal error: 'tr1/functional' file not found
#include HASH_FUN_H                 // for hash<>
         ^
/opt/local/include/sparsehash/internal/sparseconfig.h:10:20: note: expanded from macro 'HASH_FUN_H'
#define HASH_FUN_H <tr1/functional>
                   ^
1 error generated.

I've already fixed that in [18a1b6b37472aa4a717e03e70a51cac3b6fe1590/macports-ports].

There are a lot of other open tickets about shiboken which you might want to review as well.
