Why does my Perl program get a taint warning on one machine but not another?

We have two machines in our offic开发者_StackOverflow中文版e that we are using as web servers. Both are running Perl 5.10.0. We installed an open source ticketing system, OTRS, and on one machine it runs perfectly fine but on the other we are receiving the error

Insecure dependency in require while running with -T switch.

I'm mystified as to why having two identical Perl installs on both machines has one running fine and the other not. I am wondering if this is something at the system level maybe? The software installs are identical. Any advice would be appreciated. Nikki

You can read about Perl's taint mode. I suspect taint mode is enabled on one machine and it is not enabled on the other.
