Comment (by kencu):

 how to run and summarize these tests, using gcc7 as an example.

 Install the dependencies as above: `sudo port -v install dejagnu autogen
 expect`


 `sudo port -v build gcc7`

 cd {{{`port work gcc7`/build}}}

 `sudo make -k check`

 `sudo chmod -R a+rw .`

 `sudo
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc7/gcc7/work/gcc-7.2.0/contrib/test_summary
 -m YOURUSERNAME at localhost |sh`

 check your mail `mail` and save it to disk, e.g. `s 1
 ~/Desktop/gcc7.test.suite.summary.txt`
