I have not tested the following, but could it work?

1. download opennx client. It brings a matching nxclient binary IIRC
2. edit /usr/bin/x2gostartagent: find the line defining NX_CLIENT and
let the varible point to opennx nxclient.

If the nxclient is not working you have two further options:
1. use nxcl from the google neatx project
2. find a copy of the original nxclient 3.x package and use the
nxclient contained within like described above.
