site.py makes use of sys.maxsize which is not available in python 2.5
We should support 2.5 adding as release blocker
@pfmoore , @pnasrat :
sys.maxsize was added 4 months ago:
0da2c50 (by @dnozay)
we have had a few releases since adding this, should this be a release blocker?
see here: http://stackoverflow.com/questions/1405913/how-do-i-determine-if-my-python-shell-is-executing-in-32bit-or-64bit-mode
they mention this as a cross-platform/cross-version solution for detecting 64bit
$ python-32 -c 'import struct;print( 8 * struct.calcsize("P"))'
$ python-64 -c 'import struct;print( 8 * struct.calcsize("P"))'
