Changes (by duncan):

  * status:  new => closed
  * resolution:  => fixed


 This is now done. However as the last patch notes it's not all that
 convenient yet. You'd have to invoke the program like:
 $ foo_datadir="." dist/build/foo/foo
 And if the program looked at its bindir, libdir or libexecdir then those
 would need to be specified too. Someone could add a feature to cabal
 /cabal-install to launch the program or or ghci/hugs with the right env

   * Made it possible to run executeables with data files in place.
   Added an environment variable, DATA_DIR, that is checked before the
   installation data directory is used.

   * Prefix the datadir env var with the package name
   Partly as it is more likely not to clash with other users and since
   in general different libs within a program may need different paths.

 Mon May 19 18:38:08 BST 2008  Duncan Coutts <duncan at haskell.org>
   * Allow the bindir, libdir and libexec dir to be specified via env vars
   Same as for the datadir. Eg for package Foo, you'd use
   Foo_bindir=... Foo_datadir=... Foo_libexecdir=... ./Foo
   The next step would be generating a wrapper script that allows
   running the program inplace. It should also work for a library.
