Why don't you just create a ~you/local/ directory and build py2.1
there? It will take a half hour, and the improvements are
substantial. You can just tell your friends to have an alias that
points to ~you/local/bin/python for them to use it without upgrading
Just an idea, since you lose some important features with python<2.0
for numeric (such as rich comparisons: a<b for a,b arrays returns a
number in old python, but a full array of a[i]<b[i] for the newer
versions. This can make writing certain algorithms much easier and
they also perform faster as the looping is done in C).
