Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
I have already install libmemcached using
sudo yum install libmemcached

I encountered this issue trying to install the memcached gem on Amazon's AMI Linux.
I resolved it with installing both cyrus-sasl and cyrus-sasl-devel:
cyrus-sasl.i686 : The Cyrus SASL library
cyrus-sasl-devel.i686 : Files needed for developing applications with Cyrus SASL
as well as, and this is key:
gettext.i686 : GNU libraries and utilities for producing multi-lingual messages
gettext-devel.i686 : Development files for gettext
Once these were installed
sudo gem install memcached
Building native extensions. This could take a while...

On Ubuntu, try doing:
sudo apt-get install libsasl2
sudo apt-get install libsasl2-dev

I think you need to install memcache-client instead.
gem install memcache-client
and you will see this:
