Installing Fast Debugger for NetBeans 6.8 on Ubuntu 9.10

NetBeans IDE enables RoR developers to set break points in specific parts of source files. It is time consuming to use print statements to trace application development process. Because Fast Debugger uses native C extensions, gcc and some other extra packages need to be installed on your Ubuntu 9.10:

$ sudo apt-get install build-essential autoconf

Above command installed the following extra packages :
automake autotools-dev dpkg-dev fakeroot g++ g++-4.4 libstdc++6-4.4-dev m4
patch

Now you need to install ruby1.8-dev package to compile any native extensions.

$ sudo apt-get install ruby1.8-dev

Above command installed ruby1.8-dev package.
Now the ruby-debug-ide gem should build successfully.

$ gem install ruby-debug-ide
