[plt-scheme] how to create an executable for another system

Hi all,

is it possible to create executables (distributions) for other systems  
than the one you're working on? I wrote  a small utility on my Mac and  
want to give it to someone who's running Linux. Of course he could  
install scheme but it would be nicer if it was not required :-)

Alternatively, is there a way to create jar files to execute on the  
JVM? I see PLT is compilable to bytecode but it seems it uses its  
own .zo format which I suppose is different from Java class files?

Thanks a lot for any hints,
Sigrid
