Thank you very much.  I thought I had done that before.  It is
now apparent that I had used ltrace rather than strace.

Using the proper strace, of course, I can find the error!

I had been running Erlang for so long, and changed a file
permission sometime.  After the system crash I had to 
restart Erlang and then the eaccess startup problem showed.

Also, it becomes readily apparent where the 
systools:make_script() problem is when I use the proper
trace tool, so that is solved now also!

thanks again,
