[FreeNX-kNX] FreeNX on FreeBSD

[Nataraj]

yo ppl
 i got FreeNX installed at FreeBSD 6.0 from the ports collection
after successful compilation i ran
"./nxsetup --install --setup-nomachine-key
- then i could login with the regular nomachine client with a usual system
account  and i got a session list :
 session name(empty) - type (araj 192.168.x.x )-geometry (no value only a x
showing ) -status (empty)  - services ( session ID ) -- Display (1000 Na)

the resume button is greyed out , no way to connect to that session ,
nothing else happens ,

i noticed that , when entering nxagent command i got a msg libXcompext.so.1
not found , so i created symlinks from all the  /usr/X11R6/NX/lib   content
to /usr/lib
when entering ./nxagent now , i get : Fatal server error:
NXAGENT: Unable to open display ""


is that , because no local x- server configured ? ( headless server  only
running tightvnc with kde )
or what else can be the reason ? editing of the node.conf neccesary ?
