[kepler-dev] Grid Actors -- Need Help!

Hi Mr. Serra,

I cannot help you with grid-enabled workflows, but only with a comment on
your environment variable problem:
Your .bash_profile is not executed when the ExecuteCmd 
actor opens a non-interactive ssh connection to the remote machine. You
need to set your environment variables in .bashrc instead.

Hope this helps you progress on that particular path.

Kindest regards
