I was able to get the citrix reciever for arm linux working. I had the developement repos enabled.

as root
1. install as directed from install.txt for citrix
2. apt-get install libXaw.so.7
3. apt-get install libXinerama1

I downloaded a launch.ica file by logging into the WIG and right clicking on a published app.

then ran
./wfica launch.ica

note: it is not optimized for the N900 and does not let you scroll around the screen.
