As already asked in https://panel.dreamhost.com/kbase/index.cgi?area=2434, some people would like to have Python > 1.5. Your answer was: “Please install it yourself”.
Now I wonder why you don’t install Python 2.1 or 2.2 under /usr/local/python/? This way, people could use it without having to compile it and/or wasting a lot of disk space.
Even better, if you are a bit careful, you can install the newer python versions in /usr. All you have to do for this is to rename “/usr/bin/python” to /usr/bin/python1.5 and then make a link from python to python1.5. Now users could use “python” if they wanted the default version or “python” if they needed something specific.
