The 2.4.1 RPM's just move the default /usr/bin/python symlink to point to the new Python24 instead of Python23 that is the system default. You can move it back and then just point to it in the shebang in your scripts (#!/usr/bin/python24) Or you could compile 2.4 from source as I did, then you won't need to change symlinks, just install it in /usr/local/bin/python24 or something. I prefer this method, as it means you can have a seperate 2.4 install of wxPython etc (just change the LD_LIBRARY_PATH). -- http://mail.python.org/mailman/listinfo/python-list

So the only difference which occurred is that the Python 2.4 installation copied to the /usr/bin/python executable the /usr/bin/python2.4 executable ( it would seem more understandable that /usr/bin/python be a link instead ). So there is really no need to recreate it. Essentially the two versions co-exist on the system but only one can be /usr/bin/python and therefore executed when a Python script is is used as a command. >, OR make a symbolic link /usr/bin/python to /usr/bin/python2.3 > and use /usr/bin/python2.4 explicitely when you want to use the newer > version. Yes, this is the right solution. I am so used to just executing a Python script that I forgot that I could just say 'python2.4 ascript.py'. > You may also try to link modules from > /usr/lib/python2.3/site-packages to /usr/lib/python2.4/site-packages > (all or just few of them) - most should be upwards compatible. By link do you simply mean moving the unique modules in the site packages from the python2.3 directory to the python2.4 site-packages directory, or is there something else I must do to see if they work ? > It may > make Fedora utilities work again (you haven't provided error > messages, so it's hard to tell) even with Python 2.4. The errors when executed from the command line, when python2.4 is python, involved not being able to find modules, no doubt because they were not in the python2.4 site-packages subdirectory. When python2.3 is python, the modules are found and everything works. Maybe it is just a matter of moving of copying these modules on over and seeing if that fixes things. Do site-packages have to "register" themselves in any way during setup ? I do not think so, but I may be wrong. -- http://mail.python.org/mailman/listinfo/python-list
