FreeNX on fc9.x86_64

[V Pomerol]

After crossing several obstacles in getting FreeNX to work on
fc9.x86_64 I still cannot get it to run, and I would appreciate any
help on this issue.

Here is what I already did:

1. put SELinux in permissive mode (this resolved an authentication
issue reported by the freenx client, damn selinux!)

2. I followed the instructions in the following bugzilla comment
(https://bugzilla.redhat.com/show_bug.cgi?id=446816#c11).  I now have
the following two packages installed:

$ rpm -qa | grep nx
nx-3.2.0-27.fc9.i386
freenx-server-0.7.2-8.fc9.i386

3. I installed xfs and manually started the service in runlevel 3.

I can now finally run nxnode on the server.  Executing
'/usr/libexec/nx/nxnode --agent' on the server produces the following
errors:

------------------------

Does anyone have any idea on how to proceed in resolving this remaining issue?

Thanks,
