I tarred up the libraries/ .hi files on the host box:
        $ find libraries -name '*.hi'  -print > /tmp/f
        $ tar czf ghc-6.0.1-hi.tar.gz `cat /tmp/f`

copied them across, and untarred over the tree.  Also needed the
package.conf.in tweak. And I had to turn off "dl" in the
extra_libraries list of package.co.inplace (for FreeBSD).

Yay! A pretty straightforward cross-os bootstrap, from
i386-*-openbsd to i386-*-freebsd:

    $ cat hello.hs 
    import System.Info
    main = print System.Info.arch >> print System.Info.os

    $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace --numeric-version

    $ ghc/ghc-6.0.1/ghc/compiler/ghc-inplace hello.hs

    $ % ./a.out 

I'll try a cross-processor port now.
