Build fails, exception not printed to console

I'm trying to build yoavram/curveball, I get:

-----> Noticed pylibmc. Bootstrapping libmemcached.
Requirements in requirements.txt
Preparing Python interpreter (2.7.2)

in the build console and that's it.
Status is S which I thought was success but when I got to view the docs I get a 404.
