Getting sources
For building handlersocket under Ubuntu you will need to install
$ sudo aptitude install dpkg-dev libtool automake libssl-dev dpatch git-core
Create a directory where you will store all build files and get source of MySQL and handlersocket
$ mkdir build
$ cd build
$ sudo apt-get source mysql-server
$ git clone https://github.com/ahiguti/HandlerSocket-Plugin-for-MySQL.git handlersocket
That will download MySQL source into mysql-dfsg-5.1-5.1.41 and handlersocket project into handlersocket directory.
Before you start
You need to apply some Debian patches and edit MySQL configure.in
$ cd mysql-dfsg-5.1-5.1.41
$ sudo dpatch apply-all
and in file configure.in you need to add a line
#([MySQL Server], 5.1.41)
Be sure you will add your MySQL version.

Now you are ready to compile.
$ cd ../handlersocket
$ ./configure --with-mysql-source=/path/to/mysql-dfsg-5.1-5.1.41 --with-mysql-bindir=/usr/bin/ --with-mysql-plugindir=/usr/lib/mysql/plugin/
$ make
$ sudo make install
if all wend goo you should see handlersocket.so in /usr/lib/mysql/plugin/ directory
