Sorry about the confusion from my initial message, but this in on  
Linux (thus newfound ability to use HIPE), not on Mac.

Also, there's some weird environment or config thing going on.  The  
same commands, on the same machine, run via make work just fine.  But,  
at the command-line, it fails.  So, I'm trying to figure out what  
could possibly be different that would cause this.

(and, yes, binarytrees.beam is there)
