Hi @SClarkPhysics,
It actually seems that libjpeg is provided by the system in the /lib64/ (x86_64) and /lib/ (i686) directories.
However, it seems that ROOT was linked against a different version of the library, i.e. libjpeg.so.9, which seems to be provided by anaconda3.
What I propose below is a (somewhat hacky) workaround, but I think it will work. You could try the following:
$ export LD_LIBRARY_PATH=$HOME/anaconda3/lib:$LD_LIBRARY_PATH
$ root
Cheers,
J.
