How is your initial erlang installed.  One way is to git clone the source,
git checkout the version you want to install, make your changes to the file
and then make, then rename /usr/local/lib/erlang to something else, then
sudo make install and the change should take effect.  killall epmd or any
other erlang apps that might be running, then start your app.
