You can think of that one as the second edition of the 2010.1 beta
version. Agree that the directories should match. Too bad the installer
still doesn't work -- I'm working on it everyone, but the Mac installer
system is incredibly crufty and broken, and Snow Leopard broke a lot of
stuff for me.

When you mount the .dmg file a Finder window should pop up with the
install instructions in a background image. Let me guess: this isn't
working in Leopard? I should put a readme in there.

Short answer: I can't figure out how, and not for lack of trying,
either. What I do is take the binary installer that the GHC guys build
as a starting point. Despite many hours of reverse-engineering I cannot
for the life of me figure out how to extract the GHC installer package
from the binary "metapackage".
My experience has been that if you unxar the metapackage and try to copy
the included package file into a new metapackage, the mac installer
tools barf. Long-term, I'm planning on just building GHC from source so
I can package a one-click installer, but I don't have infinite time for
this project and doing psychic battle with the evil warlocks who cooked
up the Mac installer is a challenge.
If anyone has expertise in this area and a willingness to help, please
contact me off-list.

The platform installer is supposed to erase previous platform editions
before it installs itself.
