    jekyll build
/usr/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:126:in `require': cannot load such file -- jekyll-paginate (LoadError)

        from /usr/local/bin/jekyll:23:in `load'
        from /usr/local/bin/jekyll:23:in `<main>'

i have found the problem is the different location oh jekyll and gem package

whereis jekyll
jekyll: /usr/local/bin/jekyll
whereis gem
gem: /usr/bin/gem2.1 /usr/bin/gem /usr/share/man/man1/gem.1.gz

i have installed jekyll by gem and ruby package from debian repos.

Answer 1

Maybe a gem install jekyll-paginate will do the trick.
