I think that specially because of the sandbox you don't want to link  
the interpreter with your c program. The whole idea of the sandbox is  
to comunicate with the intepreter only thru a controlling program that  
uses stdin/stdout to control the pypy interpreter in a subprocess.

Take a look at the sandboxing page:


''we can translate PyPy to a special "pypy-c-sandbox" executable,  
which is safe in the sense that it doesn't do any library or system  
calls - instead, whenever it would like to perform such an operation,  
it marshals the operation name and the arguments to its stdout and it  
waits for the marshalled result on its stdin. This pypy-c-sandbox  
process is meant to be run by an outer "controller" program that  
answers these operation requests.''
