=== STEP 1 ===
--- Install Python (2.5 -> 2.7)

=== STEP 2 ===
--- Install Slick SVN (Slick-Subversion-1.6.12-win32.msi)
http://www.sliksvn.com/pub/Slik-Subversion-1.6.12-win32.msi

=== STEP 3 ===
--- Install scons 2.2.0 in the Python site-packages:
http://www.scons.org/download.php

=== STEP 4 ===
--- Install MinGW (minimalist) from sourceforge

=== STEP 5 ===
--- Install pthreads (just copy files from ftp):
ftp://sourceware.org/pub/pthreads-win32/dll-latest/
C:\pthreads\bin, C:\pthreads\include, C:\pthreads\lib

=== STEP 6 === 
--- Update libsndfile from http://www.mega-nerd.com/libsndfile  to the most recent version that works, 
which may be pre-release or release; currently it is the latest stable release (1.0.25). 
Do not build from sources.

=== STEP 7 ===
--- Update liblo tag 0.26 from the tarball at http://liblo.sourceforge.net (not SVN!), 
copy build/config-msvc.h --> src/config.h,
and build with this SConstruct:

=== STEP 8 ===
--- Install Directx 9.0 SDK (april 2007)

=== STEP 9 ===
--- Download Asio SDK

===  STEP 10 ===
--- Update the PortAudio library http://portmedia.sourceforge.net from SVN and build it. 
Try the trunk version first, if that doesn't work use the most recent tag. 

--- Copy ASIOSDK to portaudio/src/hostapi/asio

--- Check the pa_win_hostapis.c file and make sure that it is configured to build 
the DirectSound, WMME, and ASIO drivers:

--- Need to removed "volatile" from function definitions in MinGW/include/winbase.h

--- Build with this SConstruct:

###########################

--- Run the test program to ensure that the build works.

=== STEP 12 ===
--- create a file PythonXX/Lib/distutils/distutils.cfg with these lines in it:
[build]
compiler = mingw32

*** For Python 2.5, comment line 428 to 434 in Python25/include/pyconfig.py

=== STEP 13 ===
--- Download pyo sources from svn and build it with:

python setup.py install
