Comment (by AgilentGCMS):

 Replying to [comment:17 ryandesign]:
 > It gets the user and group from the prefix directory, in your case
 /Users/sbasu1/packages/macports/sonoma. Presumably when you last ran
 selfupdate, that directory was owned by the admin group.

 > I think that should be fine. You can `chmod` it to 644, change it, and
 `chmod` it back. Provided you've changed the group of
 /Users/sbasu1/packages/macports/sonoma back to `staff` it should survive
 future selfupdates.

 That's also puzzling, because when I installed macports it got installed
 as `sbasu1:staff` (going by the `port_autoconf.tcl` recovered from my
 September backup, and my `./configure` options), and currently the
 ownership of `/Users/sbasu1/packages/macports/sonoma` is still
 `sbasu1:staff` with permission 755, and I haven't manually tinkered with
 that because I never had a reason to. So I have no idea where `port
 selfupdate` got the `admin` group.

 I can confirm that manually changing the group to `staff` in
 `port_autoconf.tcl` works, i.e., `libnetpbm` upgrades successfully. I'll
 see what happens next time I `port selfupdate`. In the meantime, thanks
 for all the help :-)
