Please update gem dependency: hiredis

I was installing faye gem, but compiling failed.

gem install hiredis -v 0.3.2

Building native extensions.  This could take a while...

installed hiredis v0.4.4 without problem, but latest Faye is using >= em-hiredis v0.0.1 and em-hiredis is currently using ~> hiredis 0.3.2

I was not sure if ruby ree-1.8.7 is causing this, but work project is using ree-1.8.7 :-/

I haven't heard any other reports of hiredis failing to compile, but thanks for alerting me that there's a 0.4.x. I will take a look at upgrading when I have some time (not likely this week...), in the meantime I suggest cloning and tweaking the gemfile if that works for you. /cc @pietern

This compilation error is caused by OSX defaulting to clang instead of gcc. I'll see if the same error happens on 0.4.

hiredis 0.4 compiles fine using clang.

[mloughran]

I've just released version 0.1.1 which updates hiredis and includes a few other minor things which have been sitting around in master for ages. Please let me know if there are any issues. Cheers :)

Thanks. I'll check it out soon! :-)
