Comment (by kupietools):

 Seeing this also, although different errors:

 ```
 --->  Building spice-server
 Error: Failed to build spice-server: command execution failed
 Error: See
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports
 .org_macports_release_tarballs_ports_devel_spice-server/spice-
 server/main.log for details.
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there
 is a bug.
 Error: Processing of port spice-server failed
 ```
 The mentioned main.log is enormous and searching for errors in it didn't
 reveal anything immediately useful.
