For starters, please learn to write meaningful bug reports. Yours is concise
(a plus) but I don't have time to chase around different websites.

On my _stock Ubuntu 12.10_ I just rebuilt RInside (both 0.2.10 and the SVN
version 0.2.10.1 I have here), and run make inside examples/wt -- and it
works just fine in both cases. Try

   http://dirk.eddelbuettel.com:8088 

to play with it.  

You need to tell us (at a minimum) what OS and release, what Rcpp version,
what RInside version, possibly what Wt version etc pp.  I reckon that the
code is fine, but that something is amiss from your build.
