Perhaps tedious, but isn't it the only correct solution?

Imagine I want to use port foo which requires python 2.5, and I also  
want to use port bar which requires python 2.4. If both ports use  
"python" (or "${prefix}/bin/python") then one or the other will break  
regardless of what I python_select, not to mention that as a user of  
foo or bar I don't want to have to python_select anything; I just  
want it to work out of the box.
