PATCH 1/1 build: check for python-config in configure

From: Joel Savitz <[email protected]>

Currently, configure succeeds when python is installed without its development components, i.e. python-config and headers. The subsequent make will fail when gcc cannot locate Python.h.

This patch fixes that behavior by throwing an error at configure-time if python-config cannot be found.
