Trouble with UMUI on puma2

successfully moved to puma2, but when I try to run the UMUI this happens.
Any suggestions?

[vidale@puma2 ~]$ umui
connect /private/tmp/ Connection refused
Application initialization failed: couldn’t connect to display “localhost:65.0”
Error in startup script: invalid command name “option”
while executing
“option add *foreground $colours(enabled_fg)”
(procedure “entry_appearance” line 19)
invoked from within
(file “/home/n02/n02/umui/umui/ghui2.0/tcl/entry.tcl” line 52)

Hi Pier-Luigi,

Have you managed to get any window open on PUMA2?
Can you try running xterm, for example:

puma2$ xterm

It’s working ok from my Macbook Air.
