Redhat don't supply python 3 on RedHat 5 or 6. I don't have access to a RHEL7 
box, but if they did and you're using RHEL7 you could just "yum install" it and 
not bother with building anything.

If you're building from source you do not need to involve RPM or yum at all.
Unless you intend to ship python3 RPMs to your customers. Do you?

Otherwise you can just:

  - install the relevant library and -devel modules from RedHat, at a guess from a RHEL6 host:

      _bz2: bzip2-devel bzip2-libs
      _tkinter: tkinter tk-devel
      _lzma: xz-devel xz-libs xz-lzma-compat
      zlib: zlib zlib-devel
      _ssl: openssl openssl-devel

  - rebuild from source as before and see what it says (configure, make, etc)
