it seems you have an un-stated dependency/cies among your intermediate targets 
/ prerequisites.

Say, foo.o depends on foo.c and foo.h -- but foo.h also depends on 
generated_foo.h, which should be generated by make.

in such case, explicitly state (no recipe is necessary):


foo.h: generated_foo.h


so mk knows the `generated_foo.h' must be completed first.

-s won't help you there, because it regards processing of /command line/ 
arguments, not of prerequisites. consider:

$ NPROC=1 mk my_target

also investigate -d[egp] debug stuff.


have fun with mk, it's a great little tool :-)
