this is bsdtar 2.6.2 on 10.6 and bsdtar 2.8.3 on 10.7

correction: -J and --lzma only work with bsdtar 2.8.3 on 10.7
tar on 10.6 seems to not understand any of these options.

I assume that
- the man page is not appropriate for the implementation
- the implementation on OSX 10.7 is buggy since it does
  accept the --use-compress-program but fails.

Now, if also Lenny is not really up to date,
I'd say the most compatible way would be 
to (always) use
<compressor> -dc | tar -f -

What do you think?
