Latest Linux Installer Stalls at Pre-Installation Check 

Have unpacked and run installation script, but find it stalls continuously at the Pre-Installation check.
The two warning which are apparently really errors (since installation is not allowed to proceed) are:

Session Writeable
> session.save_path: /temp

PHP LDAP Library
> Warning Icon

Could find no online docs to provide any insight into further troubleshooting.
well dear commuity i want you to confirm that the  directory permissions are set per installation docs.

Any suggestions welcome.

by the way: 
can i go round the annoying step of the Pre-Installation check? This is pretty annoying...:
