There seems to be a "maximum-path-length" limitation in bbox-tar. I had a
similar problem with bbox-0.60.2 and 0.60.3 but got a different error-message:
	tar: Names longer than 100 chars not supported.
0.61pre-20020813 does _not_ print any error-msg but also cut's the
path-/file-names; it exits with rc=0 and _only_ skips the long names, all
other files are extraced normally.

As it is always a good idea to use the same archiver for packing and unpacking
I also compiled a static GNU tar-1.3.25.
