Problems trying to build and run sample app

[MayamaTakeshi]

Hello, I have built mad from source (latest commit 4c8f6043c6fe689851f395b0f2035151982024f1) and I am trying to experiment with a sample app as instructed:

$ mad app "sample" $ cd sample/ $ mad deps compile plan bundle "web_app"

But I am getting this:

DTL Compiling /home/takeshi/tmp/learn/mad/sample/apps/n2o_sample/priv/templates/index.html escript: exception error: undefined function erlydtl_beam_compiler:is_up_to_date/2 in function erlydtl_compiler:parse_template/2 (/home/takeshi/tmp/learn/mad/sample/deps/erlydtl/src/erlydtl_compiler.erl, line 378) in call from erlydtl_compiler:do_compile/1 (/home/takeshi/tmp/learn/mad/sample/deps/erlydtl/src/erlydtl_compiler.erl, line 474) in call from erlydtl_compiler:compile/1 (/home/takeshi/tmp/learn/mad/sample/deps/erlydtl/src/erlydtl_compiler.erl, line 206) in call from lists:foreach/2 (lists.erl, line 1336) in call from mad_compile:dep/4 (/home/takeshi/src/git/mad/src/mad_compile.erl, line 49) in call from mad_compile:deps/4 (/home/takeshi/src/git/mad/src/mad_compile.erl, line 11)

I can see this is because erlydtl_beam_compiler.beam is not being generated:

takeshi:sample$ find . -name 'erlydtl_beam_compiler.*' ./deps/erlydtl/src/erlydtl_beam_compiler.erl

But if i run make inside folder erlydtl, it gets created: takeshi:sample$ cd deps/erlydtl/ takeshi:erlydtl$ make ... ABRIDGED ... takeshi:erlydtl$ cd - /home/takeshi/tmp/learn/mad/sample takeshi:sample$ find . -name 'erlydtl_beam_compiler.*' ./deps/erlydtl/src/erlydtl_beam_compiler.erl ./deps/erlydtl/ebin/erlydtl_beam_compiler.beam

After that, I can start the app. But when I access http://localhost:8000 I get this in the erlang repl:
