How to ignore local python when building python from source

Question

When I try to build my own version of Python using:

./configure --enable-shared --prefix=/app/vendor/python-dev && make && make install

This looks to be a misfeature of the setup.py script always including /usr/local in the search path when make builds the target sharedmods.

You'll have to manually frob the setup.py, so do the...

./configure --enable-shared --prefix=/app/vendor/python-dev

...first, then edit setup.py, find lines 442, 443, and 444 which should look like this...

if not cross_compiling:
    add_dir_to_list(self.compiler.library_dirs, '/usr/local/lib')
    add_dir_to_list(self.compiler.include_dirs, '/usr/local/include')

...and comment them out so they look like this...

# if not cross_compiling
    # add_dir_to_list(self.compiler.library_dirs, '/usr/local/lib')
    # add_dir_to_list(self.compiler.include_dirs, '/usr/local/include')

...then the make should work.
