|17|| || * '''Overcoming the failure''' It may be that the mirror is temporarily down, so you'll need to download it manually. You can tell which mirror you are downloading from the output's ''Attempting to fetch xx from http://yyy/zzz'' which means you are attempting to download the file http://yyy/zzz/xx. You can navigate there in a browser and see if the file and its neighbors look normal or not. If not then report this to the mailing list or ask the mirror owner to fix their server configuration, or wait to see if it gets fixed over time. In the meantime you could try searching for that specific file, download it manually, and copy it over the top (to replace) your local downloaded version of that file (located somewhere in /opt/local/...), then attempt the install again. It should pick up the "now working" file and continue as normal. For a list of mirrors you could use, you can look in the port file ([https://trac.macports.org/browser/trunk/dports/textproc/texi2html/Portfile example]) for "master_sites" then lookup that master site in the list of [https://trac.macports.org/browser/trunk/dports/_resources/port1.0/fetch/mirror_sites.tcl master sites].
