Summary: Can't build Python on POSIX w/o $HOME

Initial Comment:
If you're building Python on os.name == 'posix' but
when there is no $HOME defined in your environment, you
cannot build Python.  This is because in the bowels of
distutils, you end up in check_environ(), which has
these lines:

    if os.name == 'posix' and not
os.environ.has_key('HOME'):
        import pwd
        os.environ['HOME'] = pwd.getpwuid(os.getuid())[5]

However, in a from-scratch build, the pwd module isn't
built by the time you get here.  I found this when
using SCons to build Python, since by default the
enclosing environment isn't passed to subprocesses.

I can work around this in my builds but Python's
setup.py should probably synthesize a $HOME if one
doesn't exist.  (Or maybe someone has a better idea for
a workaround).

Let me revise that last comment.  There are some build
differences when this is done.

Uncommenting pwd in Setup.dist allows python to build, but
the 'pwd' extension (and pwd.so) does not get built.

And pwdmodule.o is ar'd into libpython2.4.a (& linked into
libpython2.4.so)

I had this problem, too.
The fix proposed by birkenfeld on 9/22 works for me.

Seems that the pwdmodule entry in Modules/Setup.dist must be
uncommented.
