I think I know why that is happening.
This is because you are compiling ghc 6.5 using older (few weeks and more)
ghc 6.5. During this time Array-interfaces changed in base, and ghc
had to be patched for it. The fix is to either use previous release of
ghc (6.4) for stage1 or unpull/rollback patch

* Fix Array imports
for stage1. But you will need to reapply it for stage2.
I haven't tried this, but it should work :-)
