 Ok, this shows gcc being successfully extracted.

 This shows us that the next command comes from a custom post-extract block
 used by this port (or a portgroup it includes).

 This shows the problem: the port (or portgroup) is trying to run `tar
 -tf`. That's not valid for a compressed tar file on OS X versions prior to
 10.9. In order to support all OS versions, either specify the compression
 method in this command (e.g. for a tar.gz file, specify `tzf` rather than
 `tf`) or use separate decompression and extraction commands like MacPorts
 does for automatic extractions. (See the commands used in the successful
 extraction of gcc above.)
