You don't need to Cc yourself when you're the reporter. But you should Cc the maintainer of the port. I've assigned the ticket to him now.
The config.log says the reason why the C++ compiler cannot create executables is:
configure:1950: /opt/local/bin/llvm-g++-4.2 -Os -arch x86_64 -I/opt/local/include -L/opt/local/lib -Wl,-headerpad_max_install_names -arch x86_64 conftest.cc >&5
ld: library not found for -lcrt1.10.6.o
Googling this error message, I foundthis Stack Overflow post which says this could be caused by not installing the Xcode command line tools, so please ensure you've done that by running xcode-select --install
