It seems like Tk 8.5.11 is not used (something like that) when I change this line... but, I am not sure about what problems/ disadvantages I might have if I go with this installation. But temporarily it works if I do this change. I am posting this for those who have the same problem and want to make Tk work with ruby1.9.1 on ubuntu. I don't think this post would be that helpful for those trying to resolve the bug. -- Posted via http://www.ruby-forum.com/.
