This sounds like a serious bug with OpenSolaris.
But perhaps it is a bug in the script.  Can you
reproduce the problem by invoking

  truss -f -o truss.log make

and then look at truss.log and see which system calls are
going wrong and why?  If it's puzzling please feel free
to compress truss.log and send it along.
