I don't know, but that's the current behaviour:
libraries/array/Data/Array.hs:1:0:
Failed to load interface for `Prelude':
There are files missing in the `base' package,
try running 'ghc-pkg check'.
locations searched:
libraries/array/./Prelude.dyn_hi
libraries/array/./Prelude.dyn_hi-boot
libraries/array/dist-install/build/Prelude.dyn_hi
libraries/array/dist-install/build/Prelude.dyn_hi-boot
libraries/array/dist-install/build/autogen/Prelude.dyn_hi
libraries/array/dist-install/build/autogen/Prelude.dyn_hi-boot
/home/ian/ghc/darcs/ghc/libraries/base/dist-install/build/Prelude.hi

We have dependencies like this:
libraries/array/dist-install/build/Data/Array.dyn_o : \
libraries/base/dist-install/build/Prelude.dyn_hi
in libraries/array/dist-install/build/.depend-v-dyn when we really need
libraries/array/dist-install/build/Data/Array.dyn_o : \
libraries/base/dist-install/build/Prelude.hi
Making that directly is hard, but it is easy to make
libraries/base/dist-install/build/Prelude.dyn_hi : \
libraries/base/dist-install/build/Prelude.hi
which is enough to work around the problem.
Thanks
Ian
