Solaris tar will *keep* leading slashes unless you specify -p when you 
create the archive. GNU tar will *remove* leading slashes by default.

If you have an archive made with Solaris tar update might be a good 
option as mentioned above. You might also get away with some type of 
chroot setup to extract. though I have no idea what libs tar needs.

Here's a Sunmanagers' summary from 1988 on the same subject. It talks
