Which flag to use in "configure" to Change the Install location?

[Omita]

Long story short... I am installing Python 2.6 on OSX.  By default the
Library is installing here:

/Library/Frameworks/Python.framework

However, as I am using OSX Server I would ideally like the location to
be here:

/System/Library/Frameworks/Python.framework/

Do I need to use the "--libdir" flag? Or is that referring to "lib"
not "Library"?
