The above is correct as stated. That said, for the continued discussion on the
MP-dev list:
The way around this issue with MacPorts' Python 2.6 is to specify the whole
path to the executable:
$ arch -i386
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python
-c 'import sys; print(sys.maxsize)'
will print out: 2147483647. While
$ arch -x86_64 ....
will print out: 9223372036854775807. Of course, this mean that in order to
execute a python script (e.g., usrp_fft.py), one needs to specify both the
Python with full path as well as the script with full path (or '' or './' if in
the current directory)
$ arch -i386
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python
/path/to/usrp_fft.py [options]
We shouldn't be allows to have this much fun! - MLD
