1) Configure LTIB by "./ltib -c"
2) In the menu under "Package List", select "Configure busybox at build time"
3) Save/exit this configuration.
4) LTIB will unpack busybox and present its configuration.
5) In busybox's config, select "Archival utilities"
6) Scroll down to "tar".
6) Select "Enable -z option" suboption of "tar"
7) Save/exit busybox configuration

At this point busybox will be rebuilt/redeployed, and when you load hte new image, you should have a working "-z" option on tar to invoke gzip/gunzip....
