Using Python 2.4 on a 2.6 system

[audiodef]

I have python-2.6 in my system. If I need python-2.4, which I was able to emerge (2.4.6, to be exact), how do I get an ebuild to use it instead of 2.6? I'm trying to emerge something that fails because "python 2.4 is needed".

audiodef,

You make a particular version of python active by using

[Naib]

by ebuild depending on python.2 4 I take it what you mean is there is a python app that only works for python-2.4?

if that is the case there are a couple of ebuild variables you can make use of

SUPPORT_PYTHON_ABIS
RESTRICT_PYTHON_ABIS

This influence /usr/bin/python (this is actually a C-program which will then execute /usr/bin/python-2.{4,5...}

have a look at zope or plone ebuilds
both zope and plone are py-2.4 only

Thanks, guys. I don't think there's anything to fix in the ebuild, as the source code itself is telling me it wants python 2.4 - not the ebuild. Is there any way around that? It's a program that hasn't been updated since 2006, I think, and I'm not looking to maintain it myself - just write an ebuild so other people can install it from an overlay.

Using eselect to switch to python 2.4.6, a manual make still fails, so maybe that's that.

I'm looking in the zope dir of portage and there are quite a few things in there. The few ebuilds I looked at did not have those variables. Could you point me to a couple of specific ebuilds, including version, that contain these vars?

EDIT: Found it in a zodb ebuild. Trying it out now. Is there a guide somewhere on the use of these vars? I'd like to know things like whether I should use EAPI="2", etc., or anything else that may be relevant.

I tried SUPPORT_PYTHON_ABIS="1" and the compile still fails because python-2.4 is needed. Here's the ebuild:

Shouldn't it be RDEPEND="=dev-lang/python-2.4*" ?

[audiodef]

Thanks, Mike. While that fix made sure python-2.4* gets pulled in, it continues to fail with the same error.
