to my untrained eyes it looks like it is trying to rebuild gcc49, that 
it is using clang which spits out lots of warnings and the stage-1 
generated compiler itself then files to execute properly

The fatal error is:
:info:build In file included from 
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc49/gcc49/work/gcc-4.9.4/gcc/c/c-objc-common.c:33:

coulkd this be due to the latest C++ fixes of macports?
