My initial suspicion here would be the version of tar you're using. Many
versions of tar don't handle symbolic links or special files very well.
You don't mention if it had a problem with other files in /dev. Try
compiling GNU tar on the RS/6000, and see if you still have problems.

This might explain why Linux-Linux works fine (most Linux distributions
use GNU tar by default).
