Could I just check if this approach can be used to suppress example code 
including rgl calls when it is running on CRAN as part of R CMD check? I 
have a package that does not build on r-release-osx-x86_64-mavericks 
because there appears to be a problem with rgl and the examples fail:


Of course I could put all the examples inside dontrun blocks, but I do 
prefer to have them run.

Many thanks for any suggestions,
