Hey Aleksandr,

the problem is the missing hiredis dependency. On OSX run:

brew install hiredis

and on Ubuntu:

apt-get install libhiredis-dev

on other platforms:

git clone https://github.com/antirez/hiredis.git && cd hiredis && make && sudo make install && sudo ldconfig

best regards :)

Thanks a lot. Worked like a charm.

Can you add it to the README please so people don't get stuck like me? :)
