portupgrade and package skipped/failed

[Patrick Lamaiziere]

Hello,

With the new portupgrade, i've got strange result :

By sample i try to upgrade claws-mail :

# portupgrade -Rn claws-mail

failed (specify -k to force) --->  ** Upgrade tasks 26: 0 done, 4

----------------

Here, why p5-XML-SAX is skipped ? The task before, portupgrade says
that p5-XML-NamespaceSupport-1.09_1 is up-to-date. So i don't understand
why it failed.

I've got many problems of this kind.
Thanks, regards.
