>>> import distutils.sysconfig
>>> distutils.sysconfig.get_python_lib()
'/usr/lib/python2.5/site-packages'

get_python_lib(plat_specific=0, standard_lib=0, prefix=None)
        Return the directory containing the Python library (standard
or
        site additions).

        If 'plat_specific' is true, return the directory containing
        platform-specific modules, i.e. any module from a non-pure-
Python
        module distribution; otherwise, return the platform-shared
library
        directory.  If 'standard_lib' is true, return the directory
        containing standard Python library modules; otherwise, return
the
        directory for site-specific modules.

        If 'prefix' is supplied, use it instead of sys.prefix or
        sys.exec_prefix -- i.e., ignore 'plat_specific'.
