testing on platforms, was Fortran error

I think the poster is interested in being able to try the build/check on a Mac in the
fashion that Winbuilder does. That is, rather than have CRAN do all the platform checks,
is there a way to submit a package to be tested for just one platform?

It may be useful to have such a facility so package builders can test before submission,
and from my own experience I believe would help to render packages more platform neutral.

I suspect that all the pieces are in place to do this, but perhaps a nice front end is
needed. Is that something for a Google Summer of Code task?

Best,

What does 'submit a test mean'?  Any test you write can check the 
value of Sys.info()["sysname"]: it is "Darwin" on Mac OS X.
Or R.version$platform, which will be something like 
i386-apple-darwin9.8.0.
