Building Programs Again

I am going to install hmake and upgrade to ghc 5 but in the meantime I decided to use make.
I am puzzled however. Presumably building a module that imports a module needs the .hi file and therefore the makefile should be something like this:
Tagsv1.o : Tagsv1.hs
ghc -c Tagsv1.hs -package lang
Basev1.o : Tagsv1.hi Basev1.hs
ghc -c Basev1.hs -package lang
But if I do this then make complains if I want to see what it will generate
[dom@lhrtba8fd85 maketest]$ make -n
ghc -c Tagsv1.hs -package lang
make: *** No rule to make target `Tagsv1.hi', needed by `Basev1.o'. Stop.
Running make works as by the time the rule gets executed the .hi file exists.
Can anyone suggest something better?
Dominic.
