That means it's OOM-killed while linking the setup script?
That should not be (nor should it be OOM when compiling any of those
Although, I just tested and linking the default Setup.hs used 300MB here,
so 450MB is not impossible.
There's a lot to link in from the Cabal library, perhaps also the ghc-api
(the unstripped executable was 5.6MB, which is surprisingly huge, the
stripped is still 3.1MB, normally executables are smaller).

You could try installing them (and afterwards cabal-install) the old way,
$ runghc ./Setup.hs configure --user
$ runghc ./Setup.hs build
$ runghc ./Setup.hs install
But if ghc is killed linking the default setup script, it will probably get
killed each time you try to cabal install a package because that involves
linking a setup script.
