I get a similar message when i start Sciviews R console.  I do not get the
message when I start R directly or through Tinn-r .  If I load the libraries
one by one the message is returned after svViews is loaded.  I presume there
is some problem with svViews.  However it does not appear to have any
consequences for my work.  I use R 2.3.1 with Windows XP and I should have
the latest versions of packages installed
