I don't think you can export a variable to a parent process.  That is,
a script can't set the environment for the shell that calls it. 
That's why bash has the "." builtin.  Try
$ . ./beforeMaking.sh
instead.  You don't need the "#!/bin/bash" line, or for the file to be
executable, since bash is just treating the file as a series of
commands to execute, not a separate process.
