Problem in building site from repository (ubuntu)

[vahtras]

Hi
I have ubuntu 14.04 LTS and I encounter the following problem with make site:

$ make site
jekyll build -t -d _site
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future,     use String#encode instead.
/usr/lib/ruby/1.9.1/time.rb:265:in `_parse': can't convert nil into String (TypeError)
    from /usr/lib/ruby/1.9.1/time.rb:265:in `parse'
    from /usr/bin/jekyll:95:in `block (2 levels) in <main>'
    from /usr/lib/ruby/1.9.1/optparse.rb:1391:in `call'
    from /usr/lib/ruby/1.9.1/optparse.rb:1391:in `block in parse_in_order'
    from /usr/lib/ruby/1.9.1/optparse.rb:1347:in `catch'
    from /usr/lib/ruby/1.9.1/optparse.rb:1347:in `parse_in_order'
    from /usr/lib/ruby/1.9.1/optparse.rb:1341:in `order!'
    from /usr/lib/ruby/1.9.1/optparse.rb:1432:in `permute!'
    from /usr/lib/ruby/1.9.1/optparse.rb:1453:in `parse!'
    from /usr/bin/jekyll:137:in `<main>'
make: *** [_site/index.html] Error 1

So far I have only installed standard packages, jekyll and python-yaml. I have also changed the source only so that make check passes.

and

$ make check
Testing file "./index.html".
Everything seems to be in order.

I have no clue really what is going on, so I am helpful for any advice.

Problem was that the jekyll of the ubuntu package is too old and it was all solved following instructions in
http://michaelchelen.net/81fa/install-jekyll-2-ubuntu-14-04/ (thanks to Olivier Lafleur for pointing this out)

Thanks Olav - can you please send a PR against README.md (there's a FAQ
at the bottom) explaining the symptoms and the fix? We'd be happy to
take that as your contribution for instructor training...
Cheers,
Greg
