See apache/couchdb-mochiweb#5 (comment) for an explanation on why a recompiled rebar file was provided. This file can be recompiled by the following commands:

asdf install erlang R15B03-1
asdf erlang shell R15B03-1
git clone https://github.com/rebar/rebar.git
cd rebar/ && ./bootstrap
chmod +x rebar
