Well, you can't count it undoing two busybox-power symlinks against it - like every tool does that: tar will clobber busybox-power's tar symlinks last I checked, ping will definitely clobber /usr/bin/ping, etc.

It's just the nature of what busybox does: it puts symlinks to itself in a bunch of filepaths, and if you install any more full-fledged utility, you lose your symlink. Consequently, although I initially suggested considering doing something about it, on further thought I would not consider this a bug of the traceroute2 package, at all.
