If you want (or need) to have ImageMagick and imagick libs installed on your server you should do following (manual for lazy admins =):
ImageMagick installation
wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
tar zxf ImageMagick.tar.gz
cd ImageMagick-6.3.8
./configure
sudo make
sudo make install

imagick installation
wget http://pecl.php.net/get/imagick-2.1.0RC3.tgz
tar zxf imagick-2.1.0RC3.tgz
cd imagick-2.1.0RC3
phpize && ./configure
sudo make
sudo make install

Have fun
