Please describe the problem:

Jhbuild makes certain assumptions about Python module installation paths that are incorrect for Python 2.6. "site-packages" has been replaced by "dist-packages".
For sugar-jhbuild [1], I'm using distutils.sysconfig.get_python_lib(prefix='') to determine the correct path:


  # We need to add the gtk-2.0 directory explicitly to
  # the Python path since '.pth' files (here pygtk.pth)
  # only work properly in system directories
  pythonpath_basic = distutils.sysconfig.get_python_lib(prefix='').split('/', 1)[1]
  pythonpath_gtk = os.path.join(self.prefix, ["lib", "lib64"][self.use_lib64], pythonpath_basic, 'gtk-2.0')
  jhbuild.config.addpath('PYTHONPATH', pythonpath_gtk)

  # workaround for bug in jhbuild
  # note: even for use_lib64 we need "lib" here as that's where distutils installs to
  pythonpath_lib = os.path.join(self.prefix, "lib", pythonpath_basic)
  jhbuild.config.addpath('PYTHONPATH', pythonpath_lib)

  os.environ['PYTHON_LIB'] = distutils.sysconfig.get_python_lib(prefix=self.prefix)
