I cannot speak for R-Forge.R-Project.org and suggest you

  a) try to ignore this at best

  b) continue to test on your local system

On our systems, with R 2.15.*, R 3.0.0 and R 3.0.1.rc everything works just
fine with Rcpp 'as released' (ie 0.10.3) and from SVN.

If your experience is differemt, the best chance for tangible help is to
supply a reproducible example.
