rsync warning in 'sudo port -v selfupdate' (code 24)

[Takashi Yoshida]

Hi,

While I was running 'sudo port -v selfupdate', I saw something I have  
never seen before.

...
net/pen/
net/pftp/
net/pork/
net/psi/
net/roadrunner/
net/rsync-devel/
net/rsync-lart/
net/rsync-lart/files/
perl/p5-app-cli/
file has vanished: "ports/mail/t-prot/.Portfile.LbLunj" (in release)
IO error encountered - skipping file deletion

sent 94 bytes  received 286305 bytes  22911.92 bytes/sec
total size is 15801285  speedup is 55.17
rsync warning: some files vanished before they could be transferred  
(code 24) at /SourceCache/rsync/rsync-30/rsync/main.c(1161)
Error: /opt/local/bin/port: selfupdate failed: Couldn't sync the ports  
tree: sync failed doing rsync

Why did this happen? And can I just do another 'sudo port -v  
selfupdate' to get things in order?

Thank you and regards,
