I'd really appreciate if anyone can help with this problem.
I'm a newbie at this and this is the first time I've tried to use the PVM
debugger.  I'm trying to test it out on something really simple like the
hello/hello_other example, which I modified to talk to as many hosts as you
want.  It works just fine w/o the debugger, but when I run the Pvm_Spawn
command with the PvmTaskDebug parameter, I'm getting the following error
message:

pvm> spawn -> hello
[9]
1 successful
t140005
pvm> [9:t180005] Xlib: connection to "hp15:0.0" refused by server
[9:t180005] Xlib: Client is not authorized to connect to Server
[9:t180005] Error: Can't open display: hp15:0.0
[9:t180005] EOF
[9:t80005] Xlib: connection to "hp15:0.0" refused by server
[9:t80005] Xlib: Client is not authorized to connect to Server
[9:t80005] Error: Can't open display: hp15:0.0
[9:t80005] EOF
[9:tc0005] Xlib: connection to "hp15:0.0" refused by server
[9:tc0005] Xlib: Client is not authorized to connect to Server
[9:tc0005] Error: Can't open display: hp15:0.0
[9:tc0005] EOF

hp15 is the server, and I added hp11, hp12 and hp13 as the hosts.  Each of
these computers has the exact same file structure/content as the one I am
working on, same goes for their environments: they are all set to display to
hp15.

I've got this in my environment:
SESSION_SVR=hp15
DISPLAY=hp15:0.0
PVM_EXPORT=DISPLAY

The xterm that is opened by the debugger displays the following message:
use:
run
__________________________________________________
xdb: Command not found.
********
xdb terminated
hit return to close window:


I am not running the debugger correctly?  I also tried this variation:
pvm> spawn -@ -> hello, but to no avail.
I suspect maybe I'm missing something essential in my environment.

Thanks in advance,
~Alex
