[Radiance-general] Radiance-general Digest, Vol 159, Issue 12

Tue May 16 12:22:32 PDT 2017

Sorry this is giving you so much trouble. I still remember the excitement
I felt when I saw the Tutorial 0 scene appear in my rvu window the first
time! 

What *nix are you using, and which version of the Radiance installer did
you use? Also, did you follow the advice and either a) try the commands in
a new terminal window after making the changes to your ~/.bashrc, or, b)
type 'source ~/.bashrc’ in the current terminal window?
