[exim] Last Resort

Hello Everybody,

I thought that I would make use of this list as a last resort. Perhaps
other users can assist, as I am not getting any luck from our control panel
vendors and I am stuck with the DKIM vulnerability.

We are running DirectAdmin Control panel which includes Exim which can be
updated via Custombuild.

When I run a build through Custombuild OR try to build Exim from tar, I get
an error that ExtUtils-Embed is not installed.
I've installed it successfully through yum, but it still complains that it
will not build because it's missing.

I am running CentOS 6.3 64bit.

This is what I get:

Please install ExtUtils::Embed for /usr/bin/perl

Any input would be much appreciated.
