The jekyll packages is pretty minimal and the generated site by a
"jekyll new" requires more than supplied by the package. To get it to
work you either need to include the ruby package for bundler (as you
did), set GEM_HOME to some writable directory, and pull in the
development dependencies of ruby (to allow compilation of native code
gems). Or stay minimal, here's an example:
$ guix shell --pure jekyll -- jekyll new --skip-bundle testdir
New jekyll site installed in /home/me/tmp/testdir.
Bundle install skipped.
$ echo title: test title > testdir/_config.yml # drop theme and plugins
$ rm testdir/Gemfile # avoid bundler installing themes and plugins
$ echo test content >> testdir/index.markdown
$ guix shell --pure jekyll -- jekyll s --source=testdir
Configuration file: /home/me/tmp/testdir/_config.yml

I am not sure this is an issue because it does work for the minimal
approach. Unfortunately it does not really operate as expected. Maybe
the package should be altered to generate a minimal setup as in the
above example on "jekyll new"?
