It won't clean either:

% port clean --all p7zip

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.

[posita (Matt Bogosian)]

Or rather the parent directory (DOC) not having write permissions. Either way it's an issue of either overly restrictive permissions or not an aggressive enough removal process.

[ryandesign (Ryan Carsten Schmidt)]

We should fix this in MacPorts by changing the permissions in a post-extract block, but the developers of p7zip should also be informed of the problem so that they can fix their packaging process and release future versions with the right permissions.

This should be fixed in r140698.
