Error installing memcached gem

I've been struggling to install memcached gem on my Ubuntu 12.04 box. Some error came out when installing native extensions:

rlibmemcached_wrap.c: In function ‘Init_rlibmemcached’:
rlibmemcached_wrap.c:13736:3: error: implicit declaration of function ‘sasl_client_init’ [-Werror=implicit-function-declaration]
rlibmemcached_wrap.c:13736:33: error: ‘SASL_OK’ undeclared (first use in this function)
cc1: some warnings being treated as errors
make: *** [rlibmemcached_wrap.o] Error 1

A quick look at what uncle Google has to say about it didn't reveal anything at first glance. A deeper search gave me the following address:

Basically the problem is that one needs to install libsasl2-dev package for this to work.

And live is good again :)
