[Pyrex] Pyrex setting MACOSX_DEPLOYMENT_TARGET

[Adam Mercer]

Hi

I've noticed that on Mac OS X Pyrex is setting the
MACOSX_DEPLOYMENT_TARGET environment variable to 10.3  in
Pyrex/Mac/DarwinSystem.py. This is causing build errors with other
packages that use Pyrex, such as glewpy, in MacPorts:

Command output: Traceback (most recent call last):
  File "setup.py", line 43, in ?
    cmdclass = {'build_ext': build_ext}
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/core.py",
line 123, in setup
    dist.parse_config_files()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/dist.py",
line 339, in parse_config_files
    filenames = self.find_config_files()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/dist.py",
line 302, in find_config_files
    check_environ()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/util.py",
line 209, in check_environ
    os.environ['PLAT'] = get_platform()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/util.py",
line 78, in get_platform
    cfgvars = get_config_vars()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/sysconfig.py",
line 488, in get_config_vars
    func()
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/distutils/sysconfig.py",
line 373, in _init_posix
    raise DistutilsPlatformError(my_msg)
distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET
mismatch: now "10.3" but "10.5" during configure

If I remove the line that sets the deployment target then the build
fails with a different error:

Is this problem due to Pyrex or glewpy?
