Thanks for expanding further on this.  What you described was exactly what I
was referencing.  All of the stock applications work fine.  I just ran into
some problems with 3rd party stuff that didn't have specific binaries for
the 64-bit OS.

If you are going to compile items on an x86_64 box using the CentOS
x86_64 arch, there are gotchas introduced by multiple libraries.

What you want to make sure you have is a pure x86_64 build environment
to build all x86_64 files.

You may need these 2 files that are i[3,4,5,6]86 (and only these x86
files ... any others can produce badly built binaries).


What this means is, you can't run i386 items (like Open Office) on your
x86_64 machine that you want to use for building packages.

As far as all the built in server services, everything on x86_64 from a
server perspective works fine (sendmail, apache, gcc, rpm-build,
etc.) ... it is the mixing of shared libraries that will cause you
problems if you want to build.
