Bengt, thanks. Thats seems to solve my problem (if I get it working).
Unfortunately I get an "Connection refused" error, see below:


roberto-saccons-computer:~/tmp/erlaunch-2004.0309 rsaccon$ bin/erlaunch start
erlaunch v2004.0309 - execute selected Erlang functions from command line
Copyright (c)2003-2004 Cat's Eye Technologies.  All rights reserved.
Emulator started, starting erlaunch subshell.  Type ^D to exit.
roberto-saccons-computer:~/tmp/erlaunch-2004.0309 rsaccon$ bin/erlaunch ls
erlaunch: connect: Connection refused
roberto-saccons-computer:~/tmp/erlaunch-2004.0309 rsaccon$ exit
exit
Stopping emulator.  Thank you for using erlaunch!
erlaunch: connect: Connection refused
roberto-saccons-computer:~/tmp/erlaunch-2004.0309 rsaccon$



anything I am doing wrong ? Anything missing ? I just compiled
erlaunch in MacOSX 1..4.11.  and with Erlang R11B, followed the
tutorial and keep getting the error above.

regards
