Error with ./run.sh (Linux, FC5)

When I run arduino (with ./run.sh) I get a box that pops up asking where to store arduino's files. I pick a directory, click open and then it dies... This the the output:

[nikosapi@localhost linux]$ ./run.sh
java.lang.NoClassDefFoundError: javax/comm/CommDriver thrown while loading gnu.io.RXTXCommDriver

./arduino: line 51:  6183 Aborted                 java processing.app.Base

I still don't have an arduino board but I'm going to make one as soon as I get the software to work.

Please help,

Hmm, do you have a version of Sun's serial communication library anywhere? Look for comm.jar or anything with serial in the name, in your Java directories. It might be conflicting with the open-source serial library used by Arduino.
