MacPorts doesn't install any tar command. The gnutar port installs a command called gnutar, not tar.

So it sounds like the system's tar command is the one that's faulty. To verify, use:

lipo -info /usr/bin/tar

On my Snow Leopard system, I have:

$ lipo -info /usr/bin/tar
Architectures in the fat file: /usr/bin/tar are: x86_64 i386 ppc7400 

If you see output that doesn't include x86_64 and i386, then your tar command is not compatible with Lion and should be reinstalled, from your backups or by reinstalling the operating system.
