Comment (by hamishmb):

 I had this issue with gnutar on 10.4 PPC as well, which was a circular
 dependency problem, as I needed to build automake, which is when I found
 that the system tar was too old to extract automake, but gnutar also
 depended on automake.

 I just ended up building the newest version of tar that I could (1.30),
 and then forcing macports to use it by creating a symlink from
 /usr/bin/tar to my manually compiled tar in /opt/local. I'm sure that's
 not the recommended way to do things, but it seems to work fine.
