What I do is that I have the python_select package installed and then / 
opt/local/bin in my path before /usr/bin. Then you can select which  
python you want with that and CMake will pick it up.


List versions available:
$ python_select -l
Available versions:
current none python24 python25-apple

See what is currently selected:
$ python_select -s

Select a different version:
$ sudo python_select python24

Note there is also an equivalent gcc_select tool.
