The packaging of riak for ubuntu is different than homebrew & devrel.  File permissions of a few things in the `lib` directory are making it problematic to recuse copy (using FileUtils.cp_r) copy this directory as a regular user.  (`lib/app_epath.sh`) - also (`erts-5.9.1/bin/nodetool`).

In the case of the erts dir; we can create a local symlink and should be fine; however we can't use that strategy for the lib dir since we have to rewrite env.sh.  Without moving the lib dir; the test server can't rewrite the `lib/env.sh` file which is now needed to set variables for 1.4 to start.

I could not use `FileUtils.cp_r` to move parts of lib individually; but my real question is - why are there .sh files in `lib` at all?
