Centos 5.1 update blew up RT

We performed server updates last weekend, including updating Centos 5.0
to 5.1, plus all of the yum updates that go with it. Now, RT is not
working.

We don’t see any messages that stand out in our rt.log or in /var/log/.

Has anyone encountered this problem before?

What errors do you get? The bit that lets you know it’s not working…

I’ve cleared the mason cache, stopped apache, and started apache with no
luck.

It’s really strange, there doesn’t seem to be any error messages
anywhere that I can find.

I’m going to take a wild guess and say that this might fix it:

RedHat (and therefore CentOS) tends to build perl with weakened
references off. This “breaks” Scalar::Util from RT’s requirements/point
of view.

Jeff Voskamp

The RedHat support just announced me they added the ‘weaken’ sub to perl 5.8.8 as part of RHEL v5 … I did not verify yet …
