Approach 2 - writing a build.py file at installation time
---------------------------------------------------------
The last question made me think, that Approach 1 works for the three
standard installation schemes, but fails miserably if the user decides
to do anything fancy.
I implemented this approach like this:

--- snip ---
# -*- coding: UTF-8 -*-
#!/usr/bin/env python

from __future__ import with_statement

import distutils.core as core
from distutils.command.install import install as _install
import sys
import getopt
import os.path

class install(_install):
    """install command

    This specific install command will create a file 'build_config.py' which
    contains information on """
    def run(self): 
        with open('lib/foo/build_config.py', 'w') as build_fp:
            build_fp.write('# -*- coding: UTF-8 -*-\n\n')
            build_fp.write("DATA_DIR = '%s'\n"%(
                os.path.join(self.install_data, 'share')))
            build_fp.write("LIB_DIR = '%s'\n"%(self.install_lib))
            build_fp.write("SCRIPT_DIR = '%s'\n"%(self.install_scripts))
        _install.run(self)

core.setup(name='foo',
           version='0.1',
           description='Foo is Bar and Baz',
           author='Wolodja Wentland',
           ...
)
--- snip ---

Is this a good approach? Is there anything i can do better?

with kind regards
