Hi, All.

I'm testing OTRS4 on AWS instance with Amazon Linux 2015.09.

DB(MySQL) and perl modules has successfully installed. But, Web server(Apache) doesn't run well.
Apache's error logs are below.

This messages seems like this one.

Then, I commented out lines uses/depends on FindBin function in "Kernel/Config/Defaults.pm", and modified to full-path, as same as original ones.
So, Apache runs successfully, but get Internal Server Error in "installer.pl".
Following messages are This one.

Maybe, when I modify to avoid FindBin function like "Kernel/Config/Defaults.pm" makes good. But impact range is too large(over 80 files must be modify).
Do you have any idea?
