Several ports broken after upgrading to macOS 15

[fwKA-git]

After upgrading the OS I did "port migrate" which failed with the following message:

--->  Note:
    Migration finished with errors.
    The following ports could not be restored:
     - bind9 
       Skipped because its dependency cmake-bootstrap failed
     - curl 
       Skipped because its dependency cmake-bootstrap failed
     - openconnect
       Skipped because its dependency lz4 failed
     - wget
       Skipped because its dependency cmake-bootstrap failed

MacPorts 2.10.1 was already installed before. Most ports were successfully updated, except for the above. I urgently need a working openconnect for my VPN connection to the company.

The error messages look similar for each broken port:

# port install openconnect
--->  Computing dependencies for openconnect
The following dependencies will be installed: 
 gmp
 gnutls
 icu
 libxml2
 libxslt
 lz4
 nettle
