Main.log from PPC Tiger

[ballapete (Peter "Pete" Dyballa)]

The same with py38-pep517. (I just keep touching the ordinary files to work these failures.)

[jmroot (Joshua Root)]

See ​https://github.com/macports/macports-ports/pull/12975

[kencu (Ken)]

all these gnutar related tickets are basically dups of 61276.

some comprehensive solutions were proposed there, so far none accepted.

[jmroot (Joshua Root)]

I get the impression that this will be a problem for a lot of modules, maybe everything that uses flit_core, maybe more. Might be worth using strict_timestamps=False there.

Replying to kencu:

all these gnutar related tickets are basically dups of 61276.

It's not clear to me that this is tar's fault, as extracting on Big Sur also produces a PKG-INFO with a timestamp of 1 Jan 1970.

Just noting here that it is sort of the old tar's fault and sort of not. See the other ticket.
