3882	Adding libraries to an inplace GHC should JustWork(TM)	benl		"
After building the head I end up with the boot libraries built and working in `./libraries`. However, if I add a new darcs checkout to this dir (say `./libraries/parallel`) and type `make` then nothing happens. 

The trouble is that the library is missing `ghc.mk` and `GNUmakefile`. These files are created by `sh boot`, but if I do that at top-level it creates a new `ghc.mk` and `GNUmakefile` for  *all* of the libraries, instead of just the new one. This means that when I type `make` now it wants to rebuild a bunch of things unrelated to the new library.

There are some instructions at http://hackage.haskell.org/trac/ghc/wiki/Debugging/InstallingPackagesInplace but I am not keen on doing that for each additional package I need. Plan A on that page will also install packages in my local .cabal which will be a problem if I'm doing multiple builds in the same account.

What should happen, is that if I place a new library in ./libraries and type `make` then this gets built and registered with the inplace compiler, just like the ones already there.

There should also be an easy way to get and update all the libraries needed by the testsuite and nofib -- ie parallel, regex, mtl. I vaguely remember a command like `./darcs-all get --extralibs` but that doesn't work anymore. Adding a line for `libraries/parallel` to `./packages` doesn't work either because the ``darcs-all get`` script only checks `darcs.haskell.org` and not `hackage.haskell.org` as well.
