OK, I found some info here:
https://github.com/JuliaLang/pyjulia/issues/38
I tried the code suggested at the end, from ronisbr
I modified it to say:
julia = PyDLL('/usr/lib64/julia/libjulia.so', RTLD_GLOBAL)
I'm using the standard fedora 23 julia package.
rpm -qf /usr/lib64/julia/libjulia.so
julia-0.4.1-1.fc23.x86_64
Attempting to execute this on python2 gives:
[nbecker@nbecker7 pyjulia]$ python2 test1.py
