In 5.00.X you could say 'ghc-pkg --show-package=3Dstd
--field=3Dlibrary_dirs' but now in 5.02 this just says "$libdir" because
we made the package.conf file independent of the install location to
solve some problems with installation on Windows.  The value of $libdir
(aka $topdir) is passed to GHC using the -B<dir> option, which on Unix
is hardwired into the shell wrapper script 'ghc'.

So we should have an option like '--print-libdir' to get at the value of
$libdir, and then you can find out the locations of the actual libraries
and include files by interrogating ghc-pkg.  ok?
