This script tries to create a sandbox using already installed binaries.
Since these binaries can be in several different places, the script 
creates a container with symbolic links, where the binaries 
(their links, actually) are arranged as MySQL Sandbox expects them to be.

To use this version, change directory to a place where you want to 
store this symbolic links container, and invoke

  make_sandbox_from_installed X.X.XX [options]

    where X.X.XX is the version number. 
    You can then pass any options accepted by make_sandbox.
