Running the examples on SSCC's Linstat server, everything worked fine up until the final example of creating a web site. Running the final command (either with make or the long version) failed with a permission denied error on a /srv/jekyll/_site directory. As an experiment I created it and gave it 777 permissions. I then had to repeat that process for several other directories (let me know if you want full replication steps.) Then it finally ran long enough to create a bunch of files--but they were not owned by me and again failed with a permissions error. At that point I gave up.
