distutils crashing: $MACOSX_DEPLOYMENT_TARGET mismatch

[Justin S Bayer]

Hi group,

When starting a distutils script (which I mostly consider as a black
box) distutils crashes with the following traceback:

Traceback (most recent call last):
  File "pyrexcompile.py", line 50, in <module>
    cmdclass = {'build_ext': build_ext})
  File "/sw/lib/python2.5/distutils/core.py", line 125, in setup
    dist.parse_config_files()

    cfgvars = get_config_vars()

_init_posix
    raise DistutilsPlatformError(my_msg)
distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET
mismatch: now "10.3" but "10.5" during configure

The script is used to trigger pyrex compilation. I am using Pyrex
0.9.6.4.

I set the environment variable to 10.5 manually from the bash. I also
hacked the distutils script and manually set it in os.environ to 10.5.
Googling for the error message did not help a lot, either.

I am running Mac OS X 10.5 on an Intel processor. I have distutils
verison 2.5.1 running on a Python 2.5.2 installed via fink.

Any help would be greatly appreciated!

Regards,
