From 3ef8b0adb4c64b5a8611472850b4991afaf289f1 Mon Sep 17 00:00:00 2001 From: Saleem Abdulrasool Date: Wed, 30 Jan 2013 04:07:37 +0000 Subject: build: add --with-python option This adds a new --with-python option to allow configuration of the python binary for building. If not specified, $PATH will be searched for common python binary names (python, python2, python3). If specified, and the path is not executable, it will attempt to search $PATH.
