[Tinyos-help] Annoying build artifact

[David]

Hi list.

Whenever I checkout the tinyos2.x source, and then build it, one of
the source code files gets modified:
tools/tinyos/misc/tos-storage-pxa27xp30

Here's the change (I use git):

--- a/tools/tinyos/misc/tos-storage-pxa27xp30
+++ b/tools/tinyos/misc/tos-storage-pxa27xp30
@@ -1,4 +1,4 @@
-#!/Library/Frameworks/Python.framework/Versions/Current/bin/python
+#!/usr/bin/python
 # -*- python -*-
 # Copyright (c) 2005-2006 Arch Rock Corporation
 # All rights reserved.

This is annoying, I need to checkout the old version each time so that
git doesn't think I made local changes to this file.

Why does the build process modify this file? Shouldn't it modify the
file in the install destination instead?

David.
