No, those are both Linux.  Try to get it to run on Windows and Mac OS as 
well (and if possible, Solaris).

If you don't have access to Windows, submit it to
win-builder.r-project.org for testing.  Mac OS and Solaris are currently 
harder to test without setting up your own local systems.  Maybe someone 
else will report on available test systems for those platforms.
