I will give it a try, but I’m not sure I understand. For example, if I use the thisroot.sh script to setup the root environment and then I run a simple ls it will unset the DYLD_LIBRARY_PATH and then I’m back to square one. (This is similar to what I wanted to do: user loads a bash script to setup the environment for additional ROOT libraries and then starts root.)
Also, it is unreasonable for me to ask all the other users of the software to install ROOT into $HOME, so it is not a great solution.
