 To report a bug, follow the instructions in the guide:

 Error: Processing of port p7zip failed

 It won't clean either:

 {{{
 % port clean --all p7zip
 --->  Cleaning p7zip

 permission denied
 }}}

 Both of these problems look like they come down to `7zC.txt` having
 permissions of `100444`. This might be hidden in `root` installs (instead
 of user installs) because `root` might be able to remove such files
 without issue.
