You can do it portably by writing your own function.
I'm not going to do it for you, but you should check out these functions
which are useful in writing it:

 COMPILE-FILE-PATHNAME
 PROBE-FILE
 FILE-WRITE-DATE
 COMPILE-FILE
 LOAD

It won't hurt to know about IF, and > and < and a few others too,
of course. ;-)
