Hi,I have installed the linux cluster toolkit. I encounter problems (see http://software.intel.com/en-us/forums/showthread.php?t=77605&o=d&s=lr) so I'm checking my installation. I have seen in the getting_started guide of 3.2 that the libxml2-python is necessary. But in the new getting_started for 4.0 I don't see this remark anymore. Is it always required ? and for pyxml ?
