[modeller_usage] "No module named modeller"

Hi,

I am completely new to Modeller. I am using Linux and have downloaded and installed the Linux(64-bit x86_64RPM) package, as recommended at the website. I have tried to run scripts from the basic tutorial, but keep getting the following error message:

ImportError: No module named modeller

I have been trying to include the path to modeller in PATH, but have not succeeded. I have python2.7.6 installed. I would be very grateful if anyone have any ideas of what I can try!

Best regards, Cecilia
