Subject: Re: LoadError: no such file to load -- tk

I followed the guide on http://www.tkdocs.com/tutorial/install.html
and success. I use Ubuntu.

1. change to root
   sudo -i

2. Install ActiveTcl
    wget
http://downloads.activestate.com/ActiveTcl/releases/8.6.0.0b7/ActiveTcl8.6.0.0b7.295590-linux-ix86-threaded.tar.gz
    tar xzf ActiveTcl8.6.0.0b7.295590-linux-ix86-threaded.tar.gz
    cd ActiveTcl8.6.0.0b7.295590-linux-ix86-threaded
    ./install.sh

3. export PATH=$PATH:/opt/ActiveTcl-8.6
    The guide on http://www.tkdocs.com not say this.
    But this is important, unless ruby will not find tk.

4. Install libx11-dev
    open "Ubuntu Software Centre"
    search "libx11-dev"
    install it

5. compile ruby
    wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p194.tar.gz
    tar xzf ruby-1.9.3-p194.tar.gz
    cd ruby-1.9.3-p194
    ./configure && make && make install

now everything works

irb(main):001:0> require 'tk'
=> true
irb(main):002:0> Tk::TK_PATCHLEVEL
=> "8.6b2"
irb(main):003:0>
