Do not lose your time to install it on Ubuntu just trying "sudo apt-get install php5-memcached". There is something you need to do that sure installing memcached. Anyway...
Step 1.
$ sudo apt-get install memcached
Step 2.
$ sudo apt-get install php5-memcached
Step 3.
$ sudo /etc/init.d/apache2 restart
Ready!
What about some test?
<?php
error_reporting(E_ALL & ~E_NOTICE);
$mc = new Memcached();
$mc->addServer("localhost", 11211);
$mc->set("foo", "Hello!");
$mc->set("bar", "Memcached...");
$arr = array(
$mc->get("foo"),
$mc->get("bar")
);
var_dump($arr);
?>
Hoping to help someone.

Installation
Information zur Installation dieser PECL-Extension finden sie im Kapitel Installation von PECL-Extensions. Zusätzliche Informationen wie neue Releases, Downloads, Quelldateien, Maintainerinformation und ein CHANGELOG finden Sie hier: » http://pecl.php.net/package/memcached.
If libmemcached is installed in a non-standard location, use --with-libmemcached-dir=DIR switch, where DIR is the libmemcached install prefix. This directory has to contain the include/libmemcached/memcached.h file.
Zlib is required for compression support. To specify non-standard installation of Zlib, use --with-zlib-dir=DIR switch, where DIR is the Zlib install prefix.
Session handler support is enabled by default. To disable it, use --disable-memcached-session switch.
i'm planning on using membase for my website and i was really struggling to install the memcashed php client on ubuntu with pear, but actually there is an easier way:
$ sudo apt-get install php5-memcached
you dont even need to install the membase server first - this can be done afterwards. hope this helps someone!
memcached 1.0.1 will compile against libmemcached 0.34.
Due to bug http://pecl.php.net/bugs/bug.php?id=17395
memcached 1.0.2 requires libmemcached 0.39+ instead.
At present memcached-1.0.0 does not compile with libmemcached-0.38. This is apparently due to libmemcached chaning the API.
For evidence, see this bug: http://pecl.php.net/bugs/bug.php?id=17070
Note: I am encountering the same 'memcached_st' has no member named 'hash' error on a Debian lenny amd_64 box.
If your server has --enable-json=shared as mine did, this extension requires you to have extension=json.so to load properly.
