I pulled the git for pgadmin4 and I'm following the new README on debian 
jessie (python 3.4)

Although I did find a debian package for this.. README should probably 
include this as an option.

root# apt-get install virtualenvwrapper
...snip...
Setting up python-stevedore (0.14.1-1) ...
Setting up python-virtualenv (1.11.6+ds-1) ...
Setting up virtualenv-clone (0.2.5-1) ...
Setting up virtualenvwrapper (4.3.1-2) ...

And then of course the path would be different:
source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
$ mkvirtualenv pgadmin4
Running virtualenv with interpreter /usr/bin/python3.4
Using base prefix '/usr'
New python executable in pgadmin4/bin/python3.4
Also creating executable in pgadmin4/bin/python
Installing setuptools, pip...done.

As related to step 5...
In my git checkout there is no $PGADMIN4_SRC/web/config_local.py.
I do have $PGADMIN4_SRC/web/config.py though
