Upgrade of libgtop fails

[David Rowe]

I have just tried upgrading all my installed macports (which include 
Gimp). Gimp itself upgraded OK, but the upgrade of libgtop fails with 
the following message:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
root# port list outdated

For the record, I am running Tiger version 10.4.11 with Xcode 2.5 on an 
Intel-based MacBookPro.
Any suggestions on fixing this problem?

Thanks to all
