find_previous_library_location() needs testing/update on Linux

I don't use Linux, so I am not going to implement this. But a pull request is welcome

Tested on server system - not currently working. Can test if you have ideas on how to make this work on Linux.
Current results below.
Currently on R 4.3.2
