Actually I found an elegant solution to getting to ANPM on eCS 2.2 for a new installation.
1) When installing eCS 2.2 using Advance Installation, install only the POSIX framework instead of the complete RPM/YUM framework (its, I think, a menu choice in the fourth installation settings window in on the installation choices but I didn't note it exactly - its the choices window that specifies system configuration -eg. System Extensions, Documentation, Tools and Games, etc.)
2) When running ANPM for the first time (after rebooting after the initial ANPM installation), it says that no RPM/YUM installation is present, and ANPM will install it (it indicates that a working internet connection is required, which is needed by ANPM anyway).
3) It downloads a YUM base package from Arca Noae, which, when installed, contains all the most recent files to get started, with ANPM including a working Python 2.7 installation right from the start. (looked like the Arca Noae file was from August 25, 2016)
When downloading and installing, the package asks what partition you want UNIXROOT to be in - I placed it in a partition different than the eCS partition - don't know if that made any difference in the ease of installation).
But that was a lot easier that fooling around in the past with bootstraps and possibly mismatched files and dependencies.
Thought this might be useful for someone else and Best!
