mach-o, but wrong architecture Part II

I've tried to use cx-freeze with the setup.py instead of the script, same same.
Ref:
http://cx-freeze.readthedocs.org/en/latest/distutils.html#distutils

How to install cx-freeze from source to use a 32 bit version of python, in this case python2.7-32.
1. Download source from:
http://cx-freeze.sourceforge.net/
2. Untar it. tar xfv or jus doubleclick
3. build/install:

python2.7-32 setup.py build
python2.7-32 setup.py install

Then you can run cx-freeze in your 32 bit version:

python2.7-32 setup.py bdist_dmg

 No matter what, the app generated is still a 64bit version:

$ python2.7-32 setup.py bdist_dmg
$ file capturebasic
capturebasic: Mach-O 64-bit executable x86_64
$ arch -i386 ./capturebasic
arch: posix_spawnp: ./capturebasic: Bad CPU type in executable

I think the problem is that I'm installing the 64bit version of cx-freeze, even if I am running python2.7-32 setup.py build.

So, what next?
- keep banging my head against this?
- move to 64bit opencv and forget?
