php excel instalação dá erro

Question

Eu preciso instalar o php excel writer (PHPExcel) na minha máquina rodando o Ubuntu 12.04. Mas não sei quais os passos que preciso seguir.

Como posso instalá-lo?

Eu tentei

sudo pear channel-discover pear.pearplex.net
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/gd.so' - /usr/lib/php5/20090626/gd.so: cannot open shared object file: No such file or directory in Unknown on line 0

Discovering channel pear.pearplex.net over http:// failed with message: channel-add: Cannot open "http://pear.pearplex.net/channel.xml" (File http://pear.pearplex.net:80/channel.xml not valid (redirected but no location))
Trying to discover channel pear.pearplex.net over https:// instead
