The most recent snap shot failed to build on my mac.

If anyone is looking to kill a few minutes of time, I've attached my  
test script.

For the inclined, type "test test_mlock" at the command prompt. If it  
works, you'll get something similar to that below (the last test  
simple runs "ver").

octave:12> test test_mlock
y = 0
y =  1
y =  1
y =  1
