Setdest and calcdest don't seem to be very portable---it looks
like they rely on linux specific features.

   - <err.h> and err() which should be replaced with the
    more verbose (but more portable) fprintf(stderr,....)

   - the code in init() which 
    initializes their random number generator
    depends on /dev/random and the random/initstate
    library calls, neither of which are portable.
    This code could be replaced by calls to the ns random number
    generator (in rng.{cc,h}).  (There will be some loss
    in the quality of the RNG, but a big gain in portability.)

Juana, if you have patches to fix these, or if the CMU/Monarch folks
have improved this code's portability since we picked it up, please
let us know so we can get more portable code.

Thanks,
