Angry [Q] [devs] Backtrack5 and aircrack-ng

I just downloaded repacked bt5 from this forum and ran it
in commands i see aircrack-ng and airmon-ng (for wifi hack )
and i dont think our /sbin/ might be containing these files
i searched up on xda and got this link which i cant understand
can any dev help?
Oh wow, finally you found me!
