Ruby prerequisites

[mozai]

I think the list of prerequisite Ruby modules (gems?) is incomplete.

$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]
$ git clone git://...
$ cd storyboard
$ bin/storyboard
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- bundler (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from bin/storyboard:8:in `<main>'

wait, saw at the bottom of the OSX instructions: "gem install storyboard". (I am not a Ruby user, and I really should learn to follow instructions.)

$ sudo gem install storyboard
ERROR:  Error installing storyboard:
ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from extconf.rb:5:in `<main>'

Seems mkmf is missing from the Ruby dependencies. gem search mkmf -r gives two results: mkmf-lite & mkmfmf, and I don't know which is correct.

No worries about maybe glossing over some instructions. DId you use RVM to install that version of Ruby 1.9.3?

[mozai]

No; found that I already have Ruby on my workstation, with a matching major.minor.minor version number. I wish not to disrupt whatever else I may have that depends on Ruby by installing competing versions on the same workstation.

Ok, if you're on a linux machine and have Ruby 1.9.1 or Ruby 1.9.3 already, you should be able to run the following to install some of the dependencies Storyboard uses:

apt-get install ruby1.9.1-dev libxml2-dev libxslt-dev make yasm imagemagick
gem install bundler

And then for the version of FFmpeg that's required:

wget http://ffmpeg.org/releases/ffmpeg-1.1.1.tar.gz
tar xvf ffmpeg-1.1.1.tar.gz
cd ffmpeg-1.1.1
./configure && make && make install
