TVDEVS looks at the name attached to the socket and the name attached to 
your computer (in principle).  You can see the name of the socket by
doing an ls -l /tmp.  I get for example  XAS.1.gala= for tv=local:1 on 
gala.  But doing the same command you have done, TVDEVS does not insist 
on a 2n local TV but will use the pre-existing one.

I doubt that outside influences can you use local TV, message and TEK so 
you should use tv=local for everything but we need to find out why 
TVDEVS.SH is balking.

If you copy TVDEVS.SH to some work area.  Then
cd $AIPS_ROOT
rm TVDEVS.SH     (a link file)
ln -s <path to your copy of TVDEVS.SH>

cd <your work area>

edit TVDEVS.SH or take the attached copy

we might learn something....
