Unable to install SEP to Debian Linux

Hi,
 
I am following the link below to install SEP to Linux:
 
http://www.symantec.com/connect/articles/how-install-symantec-endpoint-protection-1215-ru5-linux-operating-system
 
I am using Debian Linux (kernel 3.4.67+)
 
But it fails in performing pre-check, it returns 2 errors and 1 warning: to install Java 1.5 or above and jce files, 32bits glibc library and X11 libraries are missing.
 
Then I installed openjdk-6-jre (which can be provided by Debian) and jce policy files, also glibc library. But it still return the above errors in pre-check.
 
Do anyone has any ideas why.
 
Thanks!
 
Danny
