I'm not familiar with yumex, just using plain yum and rpm. Perhaps using
this non standard package manager is what is causing all your troubles.
Could it be yumex uses hard coded (or configurable) paths and you
installed a yumex for the wrong release? Where did you get that yumex
from? And why not use plain yum? You are fitting all sorts of things
onto a system that you are not familiar with, no wonder you meet a few
bumps ;-) .

It's a rebuild from Red Hat Enterprise Linux, which is based on Fedora.
Since it's an enterprise distro it provides a limited range of packages
and they are rather dated to safeguard functional, ABI and API
compatibility for a period of 5 years.

You might want to give Fedora a try, it supports *way* more packages by
default, but I have to warn you that it used to come with the warning
that "it eats babies", in the sense that it's bleeding edge and might
have some rough edges.

I suppose that's just fallout from the issue you are having, things like
this should work out of the box assuming your hardware is not too exotic
or too new. But you have to be careful about which 3rd party repos you
enable, which is probably true for any distro that supports those.

CentOS/RHEL make you start services explicitly instead of enabling
anything by default. Are both portmap and nfs running?

yum != yumex . I'm quite sure one can screw up Ubuntu too, but if you're
more comfortable with Ubuntu then by any means use it.

If your repos are set up correctly yum should behave in a similar way.
This is why yum was added on top of rpm. The reason yum bails out is
because it cannot find those dependencies in any of the repos as they
have incorrect versions. What is the cause of that is not clear to me
but something is insisting on looking at el5 repos and it's definitely
*not* any of the packages that come with CentOS 6 by default.

If you are still interested in getting CentOS 6 running I suggest you do
a clean install and only start adding 3rd party repos once you have the
system up and running.
