Can't compile tkImg from Tk package for Ruby on Ubuntu 14.04?

Question

ruby

And now in more detail. I needed a Tk toolkit for Ruby.
I installed it via sudo apt-get install libtcltk-ruby.
At first everything worked, but when it was necessary to use it, it require "tkextlib/tkimg/jpeg"gives errors:

/usr/lib/ruby/1.9.1/tk/package.rb:86:in `rescue in require': TkPackage can't find package img::jpeg (RuntimeError)
  from /usr/lib/ruby/1.9.1/tk/package.rb:83:in `require'
  from /usr/lib/ruby/1.9.1/tkextlib/tkimg/jpeg.rb:14:in `<top (required)>'
  from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
  from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
  from /home/xo8bit/RubymineProjects/test/my_test.rb:4:in `<top (required)>'
  from -e:1:in `load'
  from -e:1:in `<main>'

I found the tkimg1.4.tar.gz package separately , but I need to build it myself, I have no experience in building / compiling, after reading the manuals on the Ubuntu forum a little, I tried:

./configure
./make

and many other methods, but nothing came of it. Please help solve the original problem with Tk in Ruby. And poke your nose if the second one has already been decided somewhere.
PS Here is what irb outputs

irb(main):002:0> require "tkextlib/tkimg/jpeg"
RuntimeError: TkPackage can't find package img::jpeg
  from /usr/lib/ruby/1.9.1/tk/package.rb:86:in `rescue in require'

Answer 1

Try to put
sudo apt-get install libjpeg libjpeg-dev

Answer 2

libjpeg-dev installed, libjpeg not found. The error is still here:

/usr/lib/ruby/1.9.1/tk/package.rb:86:in `rescue in require': TkPackage can't find package img::jpeg (RuntimeError)
  from /usr/lib/ruby/1.9.1/tk/package.rb:83:in `require'

Answer 3

See a similar problem here: https://www.ruby-forum.com/topic/4414548
As far as I could understand, the problem is that extensions from tkextlib/must be installed separately, or that the standard delivery of extensions from tcl is incomplete and it overwrites the one that is placed through the gem. You can check support with the command

ruby C:/Ruby193/lib/ruby/1.9.1/tkextlib/pkg_checker.rb

(substitute the desired path to your version of ruby)
