I just want to clear that there are two problems.

1. check that every think is there what is need to compile bb
2. what to do if something is found missing

my idea is to have a script like

which --version >/dev/null || { echo "i need which" ; exit ; }
for CMD in od
do
 which $CMD || { echo "i need $CMD" ; exit ; }
done

this can be executed manually and its done. I guess that is what denis had
in mind.
