My guess is the problem is due to an older version of GTK+. Although
cairoDevice only requires GTK+ 2.8.x (which is probably what you have
installed), the Windows binary of cairoDevice on CRAN is probably built
against GTK+ 2.10.x, just like RGtk2.
I've added a feature to cairoDevice and RGtk2 recently that will
automatically try to install the latest binary of GTK+ on Mac and Windows
when loading the library fails.
That said, I'd really like to merge cairoDevice (specifically the
RGtk2-embedding feature) with the Cairo package. Having one less package to
maintain would be nice.
