I've just cloned your repo I found several problems while trying to use it. I describe them below:
It seems like you changed the layout of the examples/ dir but didn't update your rebar.config's sub_dirs option to reflect the change. As a result, if you run "make test" no features are executed.
Running ../cucumberl inside of examples/ dir doesn't run any feature. You have to cd into each sample and run ../../cucumberl
3.There are some bugs in the cucumberl_parser:process_line function that break the execution of the features.
If you wish I can send a patch with the fix to those bugs in cucumberl_parser.
