pgAdmin 4 as Web application

I'm trying to follow
https://www.pgadmin.org/docs4/dev/server_deployment.html
to install pgAdmin 4 as web application on RHEL 6, but I didn't get very far:

There is no file "pgAdmin4.wsgi" available for download.
Did I miss something obvious?


So I tried to build from source, and failed immediately with

laurenz:~/rpmbuild/pgadmin4-1.0-beta3/runtime> qmake-qt4
Project MESSAGE: Building for QT4...
Project MESSAGE: Building for Linux/Mac...
Project MESSAGE: Using /usr/bin/python-config

I searched the web, but could not find any answers how to install
Qt Webkit on RHEL 6.

Can you help?

Yours,
