Exception running arduino on ubuntu64 12.04.2, librxtxSerial.so, wrong ELF class

Development Tools IDE 1.x

Hi

I have 64 bit ubuntu 12.04.2. I've installed arduino for linux as describe here, Arduino Playground - Linux. My original librxtxSerial.so is in /usr/lib/jni. It is librxtxSerial-2.2pre1.so. I created a soft link in that directory to the librxtxSerial64.so that came arduino. This a listing showing it:
$ ll arduino-1.0.5/lib/librxtxSerial64.so
-rw-rw-r-- 1 mike mike 182189 May 17 14:22 arduino-1.0.5/lib/librxtxSerial64.so

While trying to run arduino I get the following:

$ bash ./arduino
java.lang.UnsatisfiedLinkError: /home/mike/Downloads/arduino-1.0.5/lib/librxtxSerial.so: /home/mike/Downloads/arduino-1.0.5/lib/librxtxSerial.so: wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch) thrown while loading gnu.io.RXTXCommDriver

Any idea what else I need to change?

Thanks...

I'm wondering if I need to build everything for my system. If so, some steps to get started would be very appreciated.

Thanks...

I just built arduino as described on Google Code Archive - Long-term storage for Google Code Project Hosting. and everthing seemed to go smoothly but I still get the librxtxSerial complaint, but this time it complains about the 64 bit version:

I'll keep plugging along, if anybody has any suggestions, please let me know...

Thanks...
