well... i'm not a red hat user but as long as you used rpm(red hat package manager) to install it all you should have to do is type:
rpm -e name_of_package
but instead of typing name_of_package type the name of the package you want to remove. this is definately as-is info as i'm not a redhatter but it should send you in the right direction and no one else seems to be chirping up. good luck.
