[Rd] Ryacas check

[Gabor Grothendieck]

When I do

   Rcmd check Ryacas

on my Windows Vista system under

   R version 2.6.0 beta (2007-09-23 r42958)

it checks out fine but here:

  http://cran.r-project.org/bin/windows/contrib/checkSummaryWin.html
  http://cran.r-project.org/bin/windows/contrib/2.5/check/Ryacas-check.log

it complains about the XML package even though the XML package
*is* declared in the DESCRIPTION file.

What is wrong?
