I went thru all of those with seeing anything but strace throwing away  a 
suid on a module owned by root that does a setuid $user, then complaining 
about it.  So I wiped that, then added sudo in front.  That never exited 
but went through all the motions, so I rebooted and did a cat file.log.*|
less, again without finding a smoking gun.  The call to the starter script, 
a .py, never made it into these logs according to grep.  There was lots of 
screeching because the sudo (root) environment was so different seems to be 
the take away.  It also chowned some stuff in my home dir.

So while I've learned another way not to make a light bulb, its still dark 
here. AFAIK there is no camview-emc list, only the linuxcnc list, and this 
is a case of maybe 3 people including me doing this, all of them far more 
fluent in the various languages involved than I am. But lots will be using 
this once we get it to the It Just Works(TM) stage.

What I want to do is cut steel, or in this case, pcb's that doesn't involve 
a lot of pallet making, contact installation in the pallet, a half dozen 
tool changes that require machine recalibration subroutines to be run, and 
math to get a hole drilled halfway thru the board from one side, to exactly 
register and meet that same hole when its turned over and drilled from the 
other side.

If I switch the invocation to use an older version of camunits-emc, I am 
now seeing an error in the terminal I have not seen before.

** (camview-emc:1653): WARNING **: /usr/local/lib/camunits/halio.so: 
undefined symbol: gluOrtho2D

And I'm not sure how to fix that either, it was not an error yesterday.

Thank you.

Cheers, Gene
