Problem to install Arduino serial port driver on CentOS 6

Hello. I have a question to install ARDUINO on CentOS 6.3-x86_64. I already installed Arduino 1.0.1 tools and try to set the serial port diever followed http://arduino.cc/playground/Linux/All#NoUSB on arduino site. Unfortunately, I was stopped by “No permission to create lock file” message. In addition I couldn’t install “avr-gcc, avr-gcc-c++, avr-lib” file using “yum” Would you give me some tip and file how to install Arduino serial port driver on CentOS 6 in details? I found other Linux program such as Ubuntu, Puppy an so on. http://arduino.cc/playground/Learning/Linux I try to find some solutions to solve this problem several days. However, I couldn’t find it. Please help me.
