rabbitmq-server: build fails when Python 2.7 is not the active version

[poorsod@…]

Steps to reproduce:

sudo port select --set python python34
sudo port install rabbitmq-server

Actual results:

The build fails. Inspecting the logs reveals a syntax error coming from Python - there is a rogue print statement (the syntax changed in Python 3). Setting python27 as the active version of python solves the issue.

Expected results:

It builds using python27 even when it is not the default version.

Same problem here when python25 is active:

When selecting Python 2.6, it works.

This has been fixed. But there are now many other issues, see #47799.
