Good idea, except that some checks may depend on other
checks.

Attach a hashtable to the env ? like 
env['DEPS']={}
env['DEPS']['testlua']=critical

Make sure it makes sense and then go for it. I am
currently in the process of changing the bksys
back-end (replacing scons by something else ..).

happy hacking,
