Solved KDE4 problem

I hava a problem installing kde4:
#make BATCH=yes install clean
python3-3_3 conflicts with python2-2_3 (installs files into the same place).  Problematic file: /usr/local/bin/2to3-2
My FreeBSD version is 11.0 release amd 64. Portsnap update I made yesterday. My make.conf is empty. And I also found this bug -
Can you help me to solve this problem?
Unfortunately it's not entirely possible to have multiple versions installed. Apparently they're not that compatible with each other.

To avoid any ambiguity you can set a 'default' version. If a port depends on, for example, Python you can set it to use a specified version. This doesn't work for all ports though, some ports insist on a specific version.

Add to /etc/make.conf:
See /usr/ports/Mk/ for more information.
