This is how I got it to work on Mandriva 2006... Maybe it will work for your distro too:
1) Install openmotif from http://www.openmotif.org/
2) Google for older Citrix client (I found 7.0)
3) Install the older client
When I first installed openmotif w/9.0 client, it appeared to work. The connection manager came up, but the connection was horrible (couldn't see type, connection would quit soon after login, etc). If any of you need help with getting the old client, let me know. I might be able to send it to you...
