The message indicates that the cairoDevice package was compiled under 
a different version of R from the one you are using. (E.g. R 2.12.0 
will require API version 7, but cairoDevice will not currently 
compile under pre-2.12.0: if you try the version compiled under 2.11.x 
you do get this message.)

Did you compile this from the sources, or if not, exactly what file 
are you using?  The current CRAN binary download works for me with 
2.11.1 (i386 and x86_64).

It will only work if you have the appropriate Gtk2 package installed.
I am fairly sure the one my system is picking up is GTK_2.18.5-X11.pkg

I would make sure that you have R 2.11.1 and only that installed, then 
try again.

Not BTW a good idea: there's no need to cripple R's handling of data 
in this way.
