Comment:

 The error in the log is:

 {{{
 error: no type named 'shared_ptr' in namespace 'std'
 }}}

 I think this error means the port requires C++11.

 The log also shows this is on OS X 10.8, which uses libstdc++ by default
 which does not support C++11.

 The current MacPorts solution to this type of problem is to include the
 cxx11 portgroup by writing:

 {{{
 PortGroup cxx11 1.0
 }}}

 after the PortSystem line in the portfile. This will cause the user to be
 directed to a web page that informs them how they can resolve the problem.
