I also explicitly include \usepackage{Sweave} in my Sweave documents,  
but in addition I put a copy of the Sweave.sty file in my local texmf  
tree. After updating the TeX database, TeX/LaTeX finds the package  
file without any problem.

(Kevin: email off-list if you're not familiar with the concepts of  
"local texmf tree" and "updating the TeX database".)
