[R] cairo and rapache

[Greg Dingle]

I'm trying to get Cairo and RApache to work together on OS X leopard.

Initializing Cairo stops the whole HTTP response. Apache logs show  
this message:

Break on  
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__ 
() to debug.
The process has forked and you cannot use this CoreFoundation  
functionality safely. You MUST exec().

This reference seems to explain the problem but it is beyond me how to  
fix it.
