==Python and SCons==
As described below under [[Advanced Installation#Platform-specific installation advice | Platform-specific installation advice]], Madagascar supports the oldest non-deprecated Python version currently supported by the latest stable version of [http://scons.org/ SCons].  If your version of Python is older and you experience problems you should probably [http://www.python.org/ upgrade].

Madagascar includes the latest stable version of SCons and the configure scripts will try to install it for you in RSFROOT if you don't have it already.  However, if you have an older version of SCons the configure scripts will not try to install the newer version. Your older version might work fine, but Madagascar attempts to support only the latest stable version of SCons, so if you have problems you should upgrade.

To install the SCons bundled with Madagascar go to <tt>RSFSRC/scons</tt>, unpack the tar file, and type

<syntaxhighlight lang="bash">
python setup.py install
</syntaxhighlight>

This will install SCons in the standard location. You might need root privileges. If you don't have root privileges, or you don't want to interfere with the system SCons you can install it somewhere else with a --prefix option. A logical choice is to put it in RSFROOT like this:
 
<syntaxhighlight lang="bash">
python setup.py install --prefix=$RSFROOT
</syntaxhighlight>
