I'm not sure I understand (apologies, I'm not really a mac user). We
are using these devices in non-interactive R sessions (RApache,
RScript). So the Cairo devices can only be used on machines that have
xquartz is installed? IIRC, we had some mac server at some point that
did not have xquartz but was still capable of generating cairo based
svg and png. The r-admin manual says "cairo support (without Pango)
has been added to the binary distribution".

Well part of the problem is that even running capabilities() to see if
Cairo is available at all makes R exit. Is this really expected
