If yum exits here, it hasn't done anything except give you more 
information about what it was trying to do - it hasn't downloaded any 
package files at all by this point, just the reference information that 
lets it see which packages it needs to meet your request.

Based on the errors I see, your system is either out of date, you've got 
packages from a newer CentOS release installed, or you've got 
third-party packages installed that are newer than the official CentOS 
releases, and created in such a way as to be incompatible with some of them.

Whether you finish installing the devtools or not, I'd strongly suggest 
you run "yum check-update" and install anything from at least the "base" 
and "update" repositories.

You might try installing MIMEDefang (and many of its dependencies) from 
the RPMForge repository;  I've been using their packages instead of 
rolling my own for a while now.  See http://rpmforge.net.  Note that 
it's probably not wise to blindly install anything and everything from 
there that's offered;  while some Perl modules as shipped with stock 
RHEL/CentOS are variously broken for certain purposes, many other things 
are not.

If you have questions about installing packages, or adding repositories 
and so on feel free to contact me offlist;  this isn't really a relevant 
topic for this list.

... because no new software was installed by yum, so as far as building 
MIMEDefang nothing changed.

*nod*  I'm not sure you'll be able to make effective use of MIMEDefang 
if you're not familiar with the basics of how it's turned into a set of 
executable files from the source code you downloaded.  The bulk of the 
configuration for what MD does with your mail is done in a Perl script 
fragment, so if you're not familiar with programming at all it's going 
to be a steep learning curve.
