Well, it makes sense now that you've discovered that Python headers define
NULL and wxWindows never includes Python.h anywhere except in wxPython code.

libwxPyHelpers.so is the first thing built in the wxPython/src directory.
It hasn't been installed yet until you get to the build.py -i step, but it
does exist in the current directory.  Maybe your linker needs a "-L." ?
Setting OTHERLFLAGS="-L." in build.local might help.

By default build.py expects things to be just as they are in the CVS tree,
which is $(WXWIN)/utils/wxPython/src.  You can override this in your
build.local by setting WXPSRCDIR like this:

    WXPSRCDIR = "~/MyStuff/wxPython-2.1.11/src"


I've been updating the build instructions over the last few days to help
people around issues like this and others.  There is version as of a few
days ago at
http://starship.python.net/pipermail/wxpython-users/1999-November/001074.htm
l, and there has also been a few more changes since then.
