Summary: OSX Python cannot run in console

Initial Comment:
OS: Mac OS X 10.1
HW: Verified on G4/733 & PowerBook G4/400Version:
'Unix' Python 2.2a4 (also seen on 2.2a3)
Configured: --with-suffix=.exe --without-toolbox-glue

Python cannot run on a Mac OS X machine when the user
is logged into console mode (using ">console" as login
name).

Download .tar.gz, configure python as shown, make, make
install. Log out of Mac OS X. Log in as console user:
use ">console" as login name. Run python interactively
from the shell...

Python will fail to run and emit these errors:

KCGErrorFailure: CGSNewConnection cannot connect to server
KCGErrorFailure: CGSNewConnection cannot connect to server
KCGErrorInvalidConnection: CGSGetEventPort: Invalid
connection

I believe Python is trying to connect to the
CoreGraphics server. Why? I don't know (esp. as I've
NOT compiled the toolbox glue). Perhaps Python is
linking to a Carbon library and the library is
automatically trying to open a connection. My makefile
skills are not good enough to enable me to check.

Python compiled on OS X without the toolbox glue should
essentially be identical to any other 'unix' app
compiled for Mac OS X. Doesn't seem to be that way.

OK... Another Follow Up.

Checked the configure.in file and there is no
--without-toolbox-glue switch for configure. There is a
--disable-toolbox-glue and --enable-toolbox-glue. The line
in the README that states you should use
--without-toolbox-glue is incorrect. This is a bug in the
documentation! (easy to fix though). I've checked the newly
built executable (using --disable-toolbox-glue) with 'otool
-l' and the linkage dependencies are gone. This is good.

Unfortunately when the 'make install' stage of the build
fails with:

skipping 'gestalt' extension (up-to-date)
dyld: ./python.exe Undefined symbols:
_Gestalt
_PyMac_Error
make: *** [sharedmods] Error 67

FYI. Running 'otool -l' on the Python executable shows that
it is being linked to both:

/System/Library/Frameworks/Carbon.framework

and

/System/Library/Frameworks/Foundation.framework
Carbon.framework links in
/System/Library/Frameworks/ApplicationServices.framework/
which contains the CoreGraphics framework. I'm assuming that
 causes CoreGraphics to be initialized (guessing).

Why does a plain 'unix' build of Python link to both Carbon
and Foundation?
