Thanks to those who answered my post in the past. I have to admit that you lost me about half way through the thread.
I was able to get 2 of my systems cranked up and was about to put a third system online when I remembered it was running x64 version of OS.
Can I just recompile the code on the x64 system and put it in the same home directory used by all the systems? I'm not sharing the directory across systems, but after doing this three or four times across just 2 systems, I can see why sharing would be advantages.
