arras_render : documentation about RDL2_DSO_PATH

[nyue]

I am doing a same host arras_render to connect to the minicord on the same machine. This is to get me started and also reduce any firewall issues between nodes.

However, looking at the documentation here, it says

export RDL2_DSO_PATH=${rel_root}/rdl2dso.proxy

I thought it should be this for things to work with moonray and moonray_gui

$ env | grep RDL
RDL2_DSO_PATH=/opt/MoonRay/installs/openmoonray/rdl2dso

I recall that it should be to a path not a file, in any case, I cannot find any rdl2dso.proxy file anywhere in the /opt/MoonRay directory I have build and install.

Does anyone have insight ?
