10.6 comes with both bsdtar 2.6.2 and GNU tar 1.17 (which was the last version 
under GPLv2); change the /usr/bin/tar symlink to point to gnutar instead if you 

However, both support resource forks via the same "._FILE" mechanism (or 
FILE/rsrc/NamedFork) implemented at the filesystem level.  Quick testing 
suggests that both bsdtar and gnutar both create archives and can extract files 
with resource forks properly, and they also do fine extracting an archive 
created with the other flavor of tar.  I'm unsure of what you hope to gain, but 
you should be able to build and use gnutar 1.22 instead if you like....
