I am not sure where this message should be posted.
I am doing a project on grid computing implemented in Java.

Basically in laymans term grid computing is making powerful applicatins by using unused CPU's by networking computers. (Not important)
To do this I need to run a tool called Globus that provide much of the grid services.
I have downloaded this tool but getting some problems. It tells me that I need to:
(1) download the Grid toolkit
(2) set GLOBUS_LOCATION in your environment, and run 'build_gpt'.
How do I do this latter bit, that is set the environment??? (My environment is Linux.)
--------------------------------------------------
Here is the installation page. http://www.globus.org/gt2/install/index.html
Note only the begining of the page is relevant to me, that is upto header "Building from a Source Distribution".

In your terminal window (the same one you are doing your install from) type the following:
export GLOBUS_LOCATION=/path/to/globus/source
Then do your build_gpt.
The export command sets an "environment variable". You can make variables a part of your environment permenantly by adding export commands to your ".bash_profile" file in your home directory. (Of course all of this is assuming that you are using the bash shell, which is the default under most common Linux distro's).
One more thing, you can see all of the variables that are currently defined in your environment with the "env" command.
 
If you're gonna buy things, buy this thing and I get a fat kickback:
