"Module not found" error message is too verbose
If you run sac2c with a stale Stdlib, you get this sort of output, which is not exactly user friendly:
apex@medusa:~/apexgit/Ancillary/benchmks/UnitTests/UTShape/src$ sac2c UTShape.sac
./UTShape.sac:5:10: error:
=> cannot load module `Array'
error: module `Array' not cached
./UTShape.sac:7:9: error:
=> cannot load module `Bits'
error: module `Bits' not cached
./UTShape.sac:9:16: error:

./UTShape.sac:11:12: error:
=> cannot load module `RTClock'
error: module `RTClock' not cached
./UTShape.sac:13:11: error:

OOOOOOOPS, your program crashed the compiler 8-((
