title: Creating package that uses RcppArmadillo
body: <p>I have written functions using RcppArmadillo and inline packages, I am using windows 7, R-2.14.1 and Rtools215 are installed and the path is checked.</p>
  
  <pre><code>funs = cxxfunction(list(MHcpp = signature(…), IWcpp = signature(…),  c(code1,code2), 
  plugin="RcppArmadillo" ) # No compline and I they work fine as expected.
  
  Package.skeleton(“new”,funs) # to create the package skeleton and the dynamic libray
  # to build the package  I use
  R CMD INSTALL –build new # I get the following error
  C:/Users/samuel/Documents/R/win-library/2.14/Rcpp/lib/i386/libRcpp.a(Dimension.o
  ):Dimension.cpp:(.text+0x342): undefined reference to `_Unwind_SjLj_Unregister'
