Comment:
Yes, the build problem is a separate issue, but I needed to build it in
order to reproduce the problem :-)
Anyway, I've worked around it by using 6.10.4 instead.
It looks like what's happening is that `bin-package-db.cabal` says
{{{
build-depends: Cabal == 1.8.*
}}}
but `compiler/ghc.cabal` just says
{{{
build-depends: Cabal
}}}
I'm not entirely sure why Cabal doesn't decide to use 1.8.0.3 for ghc, but
it doesn't:
{{{

pkg="/home/ian/bindists/6.10.4/inst/bin/ghc-pkg" --with-gcc="/usr/bin/gcc"

}}}
We could fix this by passing `--constraint "Cabal == 1.8.0.3"` (or
whatever the right syntax is) whenever we configure a Cabal package (I
assume that that is a no-op if the package doesn't depend on Cabal?) but
the same thing could happen with any package we use from the bootstrapping
compiler.
I think we should punt on this for now, as building with Cabal HEAD isn't
something we support anyway.
