[rt-users] Internal server error

[Jonathan Murray]

Folks, I'm running:

RT 4.2.9
CentOS 6.7
httpd-2.2.15-47.el6.centos.x86_64

when I go to the rt URL:

Internal Server Error

I checked /opt/rt4/var/log and discovered that I needed something called

RT/Authen/ExternalAuth.pm in @INC (@INC contains:

so I got that via

cpan> install RT::Authen::ExternalAuth

seemed to work OK. Restarted the web server,

Then I got this:

I was able to get that install in

/opt/rt4/local/plugins/RT-Extension-ActivityReports/lib/RT/Extension/ActivityReports.pm

Now I'm looking for something called Ex.pm

Can someone direct me to a place where I can download that? I can't seem 
to find that specific module anywhere.

Also, if I can get that installed, is there a way to make sure that I 
can get all the dependencies associated with it? Or is the normal mode 
to just keep chasing each one individually. Happy to do that, or 
(most)anything to get this running. Sorry, absolute beginner here.

Thank you, Jonathan
