I think the Sweave default of inserting the path to Sweave.sty is the 
problem. I've checked my LaTeX books, and none of them mention this as a 
possiblity:  the argument of \usepackage is supposed to be a package 
name, not a path to a style file with the .sty chopped off.  Obviously 
some implementations support the syntax of using a path, but this is 
clearly not well supported:  there's no way I can see to specify 
perfectly legal paths, if they happen to contain characters that LaTeX 
thinks are special.

So I would say the direction we should move is for Sweave to insert just


(and possibly a comment saying where to go to find it, for people who 
don't know how to set up the include path properly).  But I wouldn't 
make a change like that at this late date for 2.7.0.
