rPython using wrong python installation on Mac OSX

Question

I\'ve installed python 2.7.8 alongside the 2.7.5 which comes with OSX 10.9.4.

Now how can I point rPython to python 2.7.8?

You can have a look at the rPython INSTALL file (sorry, perhaps I should make it more explicit). It has a section on how to install rPython using the desired Python version when several coexists. It says:

In systems where several Python versions coexist, the user can choose the Python version to use at installation time. By default, the package will be installed using the Python version given by

$ python --version

but it is possible to select a different one if the RPYTHON_PYTHON_VERSION environment variable is appropriately set.

For instance, if it is defined as

 RPYTHON_PYTHON_VERSION=3.2

it will try to use Python 3.2 (looking for python3.2 and python3.2-config in the path). If set to

 RPYTHON_PYTHON_VERSION=3

it will install against the "canonical" Python version in the system within the 3.x branch.
