I have been working on MongoDB, and wanted to try out Riak as our
system is also in Erlang. But the first installation got me stuck
with an unusable client.
The server is started and seems to run. So I grabbed the
riakc-1.0.1 package, and it didn't even compile:
x...@shanghai:~/project-workspace/erlang/basho-riak-erlang-client-a1545e5$
make
./rebar get-deps
==> basho-riak-erlang-client-a1545e5 (get-deps)
Pulling protobuffs from {hg,"http://bitbucket.org/basho/protobuffs";,

So I grabbed the repository with the command
hg clone http://bitbucket.org/basho/riak-erlang-client
and compiled it. Everything seemed to be ok, until I started
running a connection, and here's I got:
x...@shanghai:~/project-workspace/erlang/riak-erlang-client/ebin$ erl -pa

So, connection to the server seemed to be fine, but then nothing
else worked.
What gives? I'm running Ubuntu 10.10.
