gcc46 does not build

I've recently upgraded my mac os X to Yosemite, similarly with Xcode and Macports. When I try to upgrade gcc46 I get the following error message:

---> Building gcc46 Error: org.macports.build for port gcc46 returned: command execution failed Please see the log file for port gcc46 for details:
