Only the first of these is necessary. The "extralibs" package contains
various extra packages that are often supplied with GHC - unpack the
extralibs tarball on top of the source tree to add them, and they will
be included in the build automatically.
There is also currently an installer for i386/Windows and binary
distributions for x86_64/Linux and i386/Linux. More may appear later.
Please test as much as possible; bugs are much cheaper if we find them
before the release!
We expect to release in a few days, assuming no major issues are
