"mach-o, but wrong architecture" in OpenCv (Leopard)

I have installed OpenCV from this doc with CMake .My ~/.profile file is :

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/export ARCHFLAGS="-arch i386 -arch x86_64"export ARCHFLAGS="-arch i386"export VERSIONER_PYTHON_PREFER_64_BIT=yesexport VERSIONER_PYTHON_PREFER_32_BIT=noexport PATH=/opt/local/bin:/opt/local/sbin:$PATHexport PYTHONPATH=/Library/Python/2.6/site-packages:$PYTHONPATH    export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib

With import cv I have this error:

Traceback (most recent call last):File "<stdin>", line 1, in <module>  File "/usr/local/lib/python2.6/site-packages/cv.py", line 1, in <module>    from cv2.cv import *ImportError: dlopen(/usr/local/lib/python2.6/site-packages/cv2.so, 2): no suitable image found.  Did find:    /usr/local/lib/python2.6/site-packages/cv2.so: mach-o, but wrong architecture

My python architecture:

file "$( "$(which python)" -c "import sys;print(sys.executable)" )"/usr/bin/python: Mach-O universal binary with 3 architectures/usr/bin/python (for architecture x86_64):  Mach-O 64-bit executable x86_64/usr/bin/python (for architecture i386):    Mach-O executable i386/usr/bin/python (for architecture ppc7400): Mach-O executable ppc

I have read and run all answers about OpenCV and Leopard in stackoverflow but still above error.Any help about this will be appreciated.

Thanks in advance
