Howdy hurie,

Thanks for your feedback on this.  Currently, we are explicitly
conflicting with other IUS python3 builds [0].  This is because there
are several file conflicts between our builds.

/usr/bin/pydoc3
/usr/bin/python3
/usr/share/man/man1/python3.1.gz
/usr/bin/pyvenv

These files are symbolic links to similar files ending in 3.4.  Here are
our options.

1. Do nothing, and continue to only allow a single version of IUS python3 installed at a time.
2. Remove every conflicting symbolic link, forcing users to use "python3.4" instead of "python3".
3. Same as 2, but only for the previous major versions (python32, python33), and leave the generic symlinks in the latest stable version (currently python34u).
4. Manage the symbolic links via update-alternatives.

The obvious problem with 2 is that many users will expect
/usr/bin/python3 to exist, and this change has the potential for
breakage.  Utilizing update-alternatives is not something we have done
before, but we are up for considering it.  More investigation is
required.

Title:
  Multiple python3x

Status in IUS Community Project:
  New

Bug description:
  It would be great if we can install multiple of same major python
  version, like installing python3.3 and python3.4.

  Currently, installing python3.4 after python3.3 will yield :

  [vagrant@vagrant-centos6 ~]$ sudo yum install python34u
  Loaded plugins: fastestmirror

   * epel: kartolo.sby.datautama.net.id
   * ius: hkg.mirror.rackspace.com

   You could try using --skip-broken to work around the problem
   You could try running: rpm -Va --nofiles --nodigest
