From 7ce4abf5993dd8819053d0592aa2276d49b3ffb3 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Thu, 18 Aug 2011 14:43:16 +0300 Subject: [PATCH] Improve detection of Python 3.2 installations Because of ABI tagging, the library version number might no longer be exactly the Python version number, so do extra lookups. This affects installations without a shared library, such as ActiveState's installer. Also update the way to detect the location of the 'config' directory, which can also be versioned.
