Remember to fill in the Port field and to Cc the maintainer of that port.

The log you attached shows this error:

:info:build Undefined symbols for architecture x86_64:
:info:build   "___bswapdi2", referenced from:
:info:build      -exported_symbol[s_list] command line option
:info:build   "___bswapsi2", referenced from:
:info:build      -exported_symbol[s_list] command line option
:info:build ld: symbol(s) not found for architecture x86_64

We've seen that error before; see #36504, which is a duplicate of #36026.

For future reference, the log you attached is not from a clean attempt so it does not tell us much else. If this had not been a duplicate ticket, I would have asked you to please "sudo port clean apple-gcc42", then try again, then attach the new main.log so we could see the full log. However since we already know this is a duplicate we don't need that in this case.
