[Mailman-Developers] wrong path to python 3.4 while installing mailman 3

[Danil Smirnov]

I'm trying to install Mailman 3 using this manual:
http://mailman-bundler.readthedocs.org/en/latest/

After step
(venv)[root at host src]# pip install zc.buildout
(venv)[root at host src]# buildout

I've got an error
----
Installing mailman.
The executable /usr/bin/python3.4 (from --python=/usr/bin/python3.4) does
not exist
/tmp/tmpuGe9kP/run: line 2:
/usr/local/src/mailman-bundler/venv-3.4/bin/pip: File or directory not found
While:
  Installing mailman.
----

I have Python 3.4. in /usr/local/bin directory, not /usr/bin.

Please help.
