It complains at linking about -lc++ but "sudo port install libcxx" is installed.

Please attach the main.log file.

You didn't mention what OS X and Xcode versions you are using. If you're using OS X 10.11 El Capitan, please install the ld64 port with the +ld64_xcode variant ("sudo port install ld64 +ld64_xcode"), then clean clang-3.7 ("sudo port clean clang-3.7") and try again.

No need to clean clang. It should continue fine and link after setting up ld64.
