The permision on "RT/Handle" were:
++++++++++++++++++++++++++++++++++++++++++++++++
[root at host rt-2-1-61]# l /opt/rt3/lib/RT/Handle.pm
-rw-r-----    1 root     bin          2.1k Jan 22 02:01 
/opt/rt3/lib/RT/Handle.pm
++++++++++++++++++++++++++++++++++++++++++++++++

I changed this to :
++++++++++++++++++++++++++++++++++++++++++++++++
[root at host rt-2-1-61]# l /opt/rt3/lib/RT/Handle.pm
-rwxr-xr-x    1 root     bin          2.1k Jan 22 02:01 
/opt/rt3/lib/RT/Handle.pm

and, then the web interface showed up.

What are the permission supposed to be  for "/installdir/rt3/lib/RT" 
directory?
