2. Installation of PEAR Libraries

PEAR contains function libraries for PHP developers. Parts of them are used in ILIAS. The command line tool "pear5" is already installed through the php5 PEAR package. But function libraries need to be installed online separately.
Proxy settings might be necessary for using PEAR installer:
pear5 config-set http_proxy http://PROXY_IP:PROXY_PORT

Specific PEAR packages were installed the following way:
pear5 install –o PACKAGE NAME

Both packages for supporting excel export are currently in beta status. Therefore they need to be installed with separate commands:
pear5 install channel://pear.php.net/OLE-1.0.0RC1
pear5 install channel://pear.php.net/Spreadsheet_Excel_Writer-0.9.1
