I'm aware that you guys didn't create bluesmash and therefor most likely can't really do much with this info, but hell, maybe you can

In bluesmash there is an option to update the suite, however it uses slapt-get which is unknown to the current backtrack not being slack anymore.
Ofcourse this can be easily fixed with a %s/slapt-get/apt-get/g, but maybe you want to change this on the iso.
