I believe that in newer versions of Mathematica (certainly 5.x, maybe 
earlier),  loading a package with <<  does exactly the same thing as 
Needs, and there is no problem with loading twice the way there used to 
be. I have had problems getting Needs to work on some systems, and have 
gone over completely to << with no problems whatsoever.

(And oops, look at your typing error in your example of Needs -- you 
made the same mistake you were helping Amit to fix!)
