MacPorts build log

The log says:

:info:build clang: error: unable to execute command: Segmentation fault: 11
:info:build clang: error: linker command failed due to signal 2 (use -v to see invocation)
:info:build clang: note: diagnostic msg: Please submit a bug report to http://developer.apple.com/bugreporter/ and include command line arguments and all diagnostic information.
:info:build clang: note: diagnostic msg: Error generating preprocessed source(s) - cannot generate preprocessed source with multiple -arch options.

Please do that. I don't have Lion or Xcode 4 and I haven't seen this problem before so I can't assist further.
