*** SAC runtime error
*** When the stdlib was compiled for this architecture neither clock_gettime( CLOCK_REALTIME, x)  nor 
host_get_clock_service(mach_host_self(), CALENDAR_CLOCK, x) were found

I ran into this before. Rebuilt Stdlib, and it thinks we have a clock:

 * Configuration state:
 * - realtime clock:       1
 * - mach clock:           

I had this happen several days ago, and found that rebuilding sac2c and Stdlib "fixed" it. I will rebuild things again, and see what I get.
