Not portably as far as I know.  This is because in order to profile, you 
typically must instrument the code under profile, in this case Scheme 
code.  That happens at the implementation level, not the Scheme level.  
One could transform the code using a portable program, but you'd still 
have to use non-portable things for timing the functions, etc.  And 
doing that portably would also be much slower than a native solution.
