Which is either an error or just the permissions of a symbolic link to Busybox.

Do you have write permission on the destination the extracted files will be written to?
Hint: if you can create a new, empty file with 'touch filename.txt' then you do have write permission there. (and 'rm filename.txt' when done with it).
