Looking at the code, I don't think it can  be.  The current code  
treats the arguments as "platform-name [arch] [version]", so the above  
statement is only matching for darwin version 7, architecture "6".

Unfortunately, fixing this is a bit more complicated than simply  
hacking some regex matches.  The platform procedure just recasts its  
arguments in terms of a variant, so you'd have to walk the set  
notation and register multiple variants for each element.   I may  
still find time to do this, but it's more complicated than a 10 minute  
change.
