Problems in installing Netbeans IDE 6.5 on Ubuntu Intrepid [solved]

I had some problems installing the Netbeans IDE 6.5 on Ubuntu Intrepid. After running the file netbeans-6.5-python-linux.sh in the terminal, there was an error:\ \ net beans lexical error or unexpected token, expected valid token\ \ If you are facing similar problems, refer to earlier post :\ JAVA Swing and AWT applications freezing in Ubuntu\ The solution to this problem is the same as mentioned in the above post. Though I had been using Netbeans 6.1, the configuration had changed somehow! Anyways, after following the instructions, the problem should get solved.\ \ Happy Netbean-ing ..
